Stamping of Flexible, Coplanar Micro‐Supercapacitors Using MXene Inks

Abstract: The fast growth of portable smart electronics and internet of things have greatly stimulated the demand for miniaturized energy storage devices. Micro-supercapacitors (MSCs), which can provide high power density and a long lifetime, are ideal stand-alone power sources for smart microelectronics. However, relatively few MSCs exhibit both high areal and volumetric capacitance. Here rapid production of flexible MSCs is demonstrated through a scalable, low-cost stamping strategy. Combining 3D-printed stamps with arbitrary shapes and 2D titanium carbide or carbonitride inks (Ti3C2Tx and Ti3CNTx, respectively, known as MXenes), flexible all-MXene MSCs with controlled architectures are produced. The interdigitated Ti3C2Tx MSC exhibits high areal capacitance: 61 mF cm−2 at 25 μA cm−2 and 50 mF cm−2 as the current density increases by 32 fold. The Ti3C2Tx MSCs also showcase capacitive charge storage properties, good cycling lifetime, high energy and power densities, etc. The production of such high-performance Ti3C2Tx MSCs can be easily scaled up by designing pad or cylindrical stamps, followed by a cold rolling process. Collectively, the rapid, efficient production of flexible allMXene MSCs with state-of-the-art performance opens new exciting opportunities for future applications in wearable and portable electronics.

Heat-assisted incremental sheet forming: a state-of-the-art review

Abstract: Incremental sheet forming is an advanced manufacturing technique where a piece of sheet is shaped into a product by a series of small incremental localized deformations. It has revolutionized sheet shaping for small-batch production since its inception in the 1990s, providing an economical and effective alternative to sheet stamping and pressing, which are cumbersome and expensive. However, the materials with poor overall ductility at room temperatures are difficult to be formed by conventional incremental sheet forming. Therefore, several heat-assisted incremental sheet-forming methods have been developed by researchers trying to improve the formability of such materials and overcome the low geometrical accuracy as well. The aim of this paper is to provide a state-of-the-art review on the development of heat-assisted incremental sheet forming. It is hoped that the knowledge provided in this paper can facilitate readers working in this field to obtain a comprehensive view and take a step forward for future incremental forming of hard-to-deform materials at elevated temperatures.

Flow and friction behaviors of 6061 aluminum alloy at elevated temperatures and hot stamping of a B-pillar

Abstract: The flow and friction behaviors of 6061 aluminum alloy (Al6061) at elevated temperatures were investigated to form a B-pillar by hot stamping with Al6061 sheets. The modified Arrhenius and Cowper–Symonds model were developed based on hot tensile tests at temperatures of 350–500 °C and strain rates of 0.01–1 s−1. The coefficients of friction (COF) at temperatures of 300–500 °C were also measured. The tribological test results show that the COF ranged from 0.95 to 1.05 with a loading force of 1 N and from 1.2 to 1.53 with a loading force of 10 N. Finally, hot stamping of a B-pillar using Al6061 sheets with different solution heat treatment temperatures and lubricants was conducted. Stamping experiments show that the B-pillar wrinkled badly and cracked in cold stamping with or without lubricants. The B-pillar also cracked in hot stamping without lubricants, but B-pillars without cracks could be obtained under lubricated conditions. Further finite element simulations with the implementation of Cowper–Symonds constitutive equation and the tested COF values (as references) were used to investigate the crack mechanisms that arise in hot stamping. Simulation results show that the crack was due to adverse friction and large temperature difference between the sidewall and rounded corners caused by non-uniform cooling. Lubrication not only reduces the friction to promote metal flow but also weakens the temperature difference. Thus, parts without cracks can be obtained.

2D material printer: a deterministic cross contamination-free transfer method for atomically layered materials

Abstract: Precision and chip contamination-free placement of two-dimensional (2D) materials is expected to accelerate both the study of fundamental properties and novel device functionality. Current deterministic transfer methods of 2D materials onto an arbitrary substrate deploy viscoelastic stamping. However, these methods produce (a) significant cross-contamination of the substrate inherent from typical dense sources of 2D material flakes and (b) are challenged with respect to spatial alignment, and (c) multi-transfer at a single step. Here, we demonstrate a novel method of transferring 2D materials resembling the functionality known from printing; utilizing a combination of a sharp micro-stamper and viscoelastic polymer, we show precise placement of individual 2D materials resulting in vanishing cross-contamination to the substrate. Our 2D printer-method results in an aerial cross-contamination improvement of two to three orders of magnitude relative to state-of-the-art transfer methods from a source of average area for single flake (~50 µm2). Moreover, we find that the 2D material quality is preserved in this transfer method. Testing this 2D material printer on taped-out integrated Silicon photonic chips, we find that the micro-stamper stamping transfer does not physically harm the underneath Silicon nanophotonic structures such as waveguides or micro-ring resonators receiving the 2D material. We further demonstrate functional devices such as Graphene tunnel junctions and transistors, and TMD-based material tunable microring resonators. Such accurate and substrate-benign transfer method for 2D materials could be industrialized for rapid device prototyping due to its high time-reduction, accuracy, and contamination-free process.

Challenges in the formability of the next generation of automotive steel sheets

Abstract: Improving strength may lightweight car bodies by thinning the structure gauge while bearing the same crash loads. Development of the third generation advanced high-strength steels aiming to boost material ductility to over 30% total elongation has become the common sense of potential solutions for stamping. Not only total elongation but also several other parameters, involving presswork hardening, anisotropy ratio, strain rate sensitivity, uniform elongation, edge sensitivity and internal stress between phases, are critical in determining the formability under the complex stress and strain distributions during stamping. We clarify here the logic of formability and difficulties in this context of three types of steel: quenching and partitioning, δ-transformation-induced plasticity and medium Mn-TRIP.

Multiscale and Uniform Liquid Metal Thin-Film Patterning Based on Soft Lithography for 3D Heterogeneous Integrated Soft Microsystems: Additive Stamping and Subtractive Reverse Stamping

Abstract: DOI: 10.1002/admt.201800061 to healthcare.[5,6] Unlike conventional solid-state electronics, soft electronics can be lightweight, stretchable, and reconfigurable, with biocompatible characteristics for skin-mountable and wearable sensing electronics.[7,8] Thereby, flexible and stretchable characteristics are achieved by using either 2D or 3D compliant wave-like, solid metal patterns[9,10] or elastic conductors based on conductive nanomaterials embedded in a polymer matrix.[11,12] An alternative approach to realize all-soft microsystems is the use of intrinsically soft conductors, such as gallium-based liquid metal (eutectic gallium–indium alloy, EGaIn). EGaIn-based soft electronics benefits from its nontoxicity, mechanical stability (unlimited stretchability, but ultimately limited by the mechanical properties of the encasing material), thermal conductivity (κ = 26.6 W m−1 K−1), and electrical conductivity (σ = 3.4 × 106 S m−1).[13–15] The low melting temperature (MP < 15 °C) and negligible vapor pressure of EGaIn facilitate room-temperature and ambient pressure manufacturing processing.[13–15] Moreover, thanks to the formation of a thin oxide layer (t ≈ 1–3 nm) on the EGaIn surface under atmospheric oxygen level, EGaIn structures maintain their mechanical shapes,[16,17] allowing 2D/3D EGaIn patterns on a soft elastomeric substrate, such as poly(dimethylsiloxane) (PDMS). The moldable characteristic of EGaIn has enabled a broad range of patterning methods based on lithography-enabled stamping and stencil printing, injection, as well as additive and subtractive direct write/patterning processes,[18–20] as summarized in Table S1 in the Supporting Information. Thereby, printing using lithography-defined stencils[21–24] yields simple and high throughput EGaIn patterning on elastomeric substrates with small features of w (width) ≈200 μm/t (thickness) ≈50 μm using metal stencil films,[21] w ≈ 20 μm/t ≈ 2 μm using microfabricated metal stencil films,[22] and w ≈ 20 μm/t ≈ 10 μm using polymer stencil films.[23] Limitations of this approach are the relatively low resolution, rough EGaIn surface, and excessive EGaIn loss during the stencil lift-off process. Subtractive The use of intrinsically soft conductors, such as gallium-based liquid metal (eutectic gallium–indium alloy, EGaIn), has enabled bioinspired and skin-like soft electronics. Thereby, creating patterned, smooth, and uniform EGaIn thin films with high resolution and size scalability is one of the primary technical hurdles. Soft lithography using wetting/nonwetting surface modifications and 3D heterogeneous integration can address current EGaIn patterning challenges. This paper demonstrates multiscale and uniform EGaIn thin-film patterning by utilizing an additive stamping process for large-scale (mm–cm) soft electronics and a subtractive reverse stamping process for microscale (μm–mm) soft electronics. While EGaIn patterning based on stamping is regarded as the least reliable patterning technique, this paper highlights multiscale and uniform thin-film patterning by stamping at room temperature and under atmospheric pressure utilizing proper chemical/physical surface modification to obtain selective nonwetting or uniform wetting properties. By combining structures fabricated using these additive and subtractive stamping techniques with 3D heterogeneous integration, functional soft microsystems are demonstrated: i) a soft LC (inductor-capacitor) sensing platform with high areal capacitance, ii) a fingertip-mountable biological sensing platform, and iii) soft heaters with localized and distributed heating capability. The demonstrated fabrication and integration approaches enable high-density and multifunctional soft microsystems for versatile sensing applications. Soft Electronics

Gradient-based multi-component topology optimization for stamped sheet metal assemblies (MTO-S)

Abstract: This paper presents a continuous relaxation of our previous work on the multi-component topology optimization, which enables the use of efficient gradient-based optimization to attain the simultaneous optimization of a base structural topology and its decomposition. In addition to the fictitious material density used in the classic SIMP method, new design variables specifying fractional membership to each component are introduced, in order to relax the process of decomposing a candidate structural topology into a discrete number of components. The concept of joint stiffness is also relaxed using the new component membership variables. Considering stamped sheet metal assemblies jointed by the resistance spot-welding, the stamping die cost consists of die-set material cost and die machining cost. The former is modeled as the minimum bounding box area enclosing each component, approximated by a product of weighted variances in major and minor directions obtained by a weighted principal component analysis. The latter is modeled as an empirical shape complexity index similar to the one available in the literature. Examples on compliance minimization of multi-component sheet metal assemblies are presented, where the proposed continuous relaxation formulation solved by a gradient-based optimization algorithm generated comparable results with dramatically improved computational efficiency over our previous results by discrete formulations solved by the genetic algorithm.

Towards a 2D Printer: A Deterministic Cross Contamination-free Transfer Method for Atomically Layered Materials

Abstract: Precision and chip contamination-free placement of two-dimensional (2D) materials is expected to accelerate both the study of fundamental properties and novel device functionality. Current transfer methods of 2D materials onto an arbitrary substrate deploy wet chemistry and viscoelastic stamping. However, these methods produce a) significant cross contamination of the substrate due to the lack of spatial selectivity b) may not be compatible with chemically sensitive device structures, and c) are challenged with respect to spatial alignment. Here, we demonstrate a novel method of transferring 2D materials resembling the functionality known from printing; utilizing a combination of a sharp micro-stamper and viscoelastic polymer, we show precise placement of individual 2D materials resulting in vanishing cross contamination to the substrate. Our 2D printer-method results show an aerial cross contamination improvement of two to three orders of magnitude relative to state-of-the-art dry and direct transfer methods. Moreover, we find that the 2D material quality is preserved in this transfer method. Testing this 2D material printer on taped-out integrated Silicon photonic chips, we find that the micro-stamper stamping transfer does not physically harm the underneath Silicon nanophotonic structures such as waveguides or micro-ring resonators receiving the 2D material. Such accurate and substrate-benign transfer method for 2D materials could be industrialized for rapid device prototyping due to its high time-reduction, accuracy, and contamination-free process.

Investigation into the Fiber Orientation Effect on the Formability of GLARE Materials in the Stamp Forming Process

Abstract: Glass-reinforced aluminum laminate (GLARE) is a new class of fiber metal laminates (FMLs) which has the advantages such as high tensile strength, outstanding fatigue, impact resistance, and excellent corrosion properties. GLARE has been extensively applied in advanced aerospace and automobile industries. However, the deformation behavior of the glass fiber during forming must be studied to the benefits of the good-quality part we form. In this research, we focus on the effect of fiber layer orientation on the GLARE laminate formability in stamp forming process. Experimental and numerical analysis of stamping a hemisphere part in different fiber orientation is investigated. The results indicate that unidirectional and multi-directional fiber in the middle layer make a significant effect on the thinning and also surface forming quality of the three layer sheet. Furthermore, the stress-strain distribution of the aluminum alloy and the unique anisotropic property of the fiber layer exhibit that fiber layer orientation can also affect the forming depths as well as the fracture modes of the laminate. According to the obtained results, it is revealed that multi-directional fiber layers are a good alternative compared to the unidirectional fibers especially when a better formability is the purpose.

Advance on friction of stamping forming

Abstract: Stamping forming is a method of pressure processing that has been widely applied to automotive manufacturing, household electrical appliance production, aviation, and other fields. Stamping friction plays a substantial role in the quality of stamping forming and the service life of the die. However, the problem of friction in stamping forming has not yet been solved due to several critical difficulties. In particular, with the application of hot forming technology and new lightweight materials in stamping forming, such as advanced high-strength steel sheets, aluminum alloy sheets, and carbon fiber materials, stamping friction has become more complex. Therefore, it is of paramount practical significance to study stamping friction. In this paper, state of the art research concerning the mechanism and factors influencing friction in stamping forming is reviewed. Investigations of the friction mechanism are described, starting by introducing the development process of traditional and modern friction theory. The present friction mechanism fails to adequately describe the frictional process occurring in stamping forming due to complex and variable factors. A survey of existing works reveals several gaps in the study of factors that influence stamping forming: the friction model is very fragile; the accuracy is not high because only a few factors are considered; and more importantly, some important factors are often ignored, such as temperature and coating. Therefore, different dynamic friction models with multifactor coupling should be established for different stamping processes and materials to fully reflect the characteristics and mechanisms of stamping friction. The present review is aimed at providing an insight into the shortcomings of the existing research background, and it demonstrates the enormous potential for further investigation and innovation in the field of friction of stamping forming.

Effect of Heat Treatment Conditions on Mechanical Properties and Precipitates in Sheet Metal Hot Stamping of 7075 Aluminum Alloy

Abstract: Due to the low formability at room temperature, the application of 7XXX aluminum alloy sheet is limited. The hot forming-quenching process is an effective technology for the forming of some complex-shaped aluminum alloy parts. In this study, heat treatment was integrated with sheet metal stamping to improve formability and strength of 7075 aluminum alloy sheet. The effect of different heat treatment parameters on the strength of 7075 aluminum alloy sheet was investigated under stamping and heat treatment integrated process, based on which the optimal heat treatment combination was determined. Furthermore, the evolution of precipitates with the variation of aging temperature and time was studied by transmission electron microscope. In addition, quenching under water-cooled dies was conducted for 7075 aluminum alloy sheet after solution heat treatment, in which the hardness under die quenching was compared with that of underwater quenching and air quenching. Finally, the tensile test illustrates that, after die quenching and successive artificial aging, the tensile strength of 7075 aluminum alloy sheet was achieved at around 548 MPa. Shear fracture with long strip step-shaped pattern was observed in aging state.

Ordered Topographically Patterned Silicon by Insect-Inspired Capillary Submicron Stamping

Abstract: Insect-inspired capillary submicron stamping and subsequent surface-limited metal-assisted chemical etching (MACE) with ammonium bifluoride as a HF source are employed for the high-throughput production of ordered topographically patterned silicon (tpSi). Insect feet often possess hairy contact elements through which adhesive secretion is deployed. Thus, arrays of adhesive secretion drops remain as footprints on contact surfaces. Stamps for insect-inspired capillary submicron stamping having surfaces topographically patterned with contact elements mimic the functional principles of such insect feet. They contain spongy continuous nanopore networks penetrating the entire stamps. Any ink (organic or aqueous) may be supplied from the backside of the nanoporous stamps to the contact elements. We generated ordered arrays of submicron AgNO3 dots extending square millimeters on Si by manual stamping with cycle times of a few seconds under ambient conditions; at higher load, ordered holey AgNO3 films were obtaine...

Electromagnetic impulse calibration in V-shaped parts

Abstract: In this study, a 2D finite-element model of electromagnetic impulse calibration was established to understand the mechanistic of springback correction. According to the results both in experiment and simulation, the springback angle after the coil discharging sharply decreases in comparison with quasi-static stamping, and the springback angle decreases gradually with the increasement in discharging energy. Finally, negative springback under the 6-KJ condition both occur in experimental and simulation results. It was found the sheet corner moves far away from punch by magnetic force and the inertial effect caused by magnetic force firstly. When the sheet peak reaches the maximum position, the sheet corner immediately reverse bending and moves closer to the punch. The phenomenon of reverse bending generates additional tangential stress in opposite direction, which decreases the original tangential stress on sheet corner and even makes the sheet corner undergo plastic deformation in high discharge energy. The discoveries showed in this paper will provide theoretical basis for controlling the springback of complex parts in the future.

Numerical Prediction of Forming Car Body Parts with Emphasis on Springback

Abstract: Numerical simulation is an important tool which can be used for designing parts and production processes. Springback prediction, with the use of numerical simulation, is essential for the reduction of tool try-outs through the design of the forming tools with die compensation, therefore, increasing the dimensional accuracy of stamped parts and reducing manufacturing costs. In this work, numerical simulation was used for performing the springback analysis of car body stamping made of aluminium alloy AA6451-T4. The finite element analysis (FEM) based software PAM-STAMP 2G was used for performing the forming and springback simulations. These predictions were conducted with various combinations of material models to achieve accurate springback prediction results. Six types of yield functions (Barlat89, Barlat2000, Vegter-Lite, Hill90, Hill48 isotropic, and Hill48 orthotropic) were used in combination with the Voce hardening model. Springback analysis was conducted in three sections of the formed part; the numerical results were compared with the experimental values. It was found that the combinations of Barlat’s yield functions and the Voce hardening law were most accurate in terms of springback prediction. Additionally, it was found that the phenomena that were investigated, which are required for the determination of the kinematic hardening model, such as the change of Young’s modulus E, the transient behaviour, work-hardening stagnation, and permanent softening, were not observed in the aluminium alloy studied.

Effects of Testing Method on Stretch-Flangeability of Dual-Phase 980/1180 Steel Grades

Abstract: Challenging fuel economy and safety standards in the automotive industry have led to the need for materials with higher strength while maintaining levels of formability that meet component manufacturing requirements. Advanced high-strength steels, such as dual-phase steels with tensile strengths of 980 MPa and 1180 MPa, are of interest to address this need. Increasing the strength of these materials typically comes at the expense of ductility, which may result in problems when stamping parts with trimmed or sheared edges, as cracking at the sheared edge may occur at lower strains. Here, hole expansion tests were performed with different punch geometries (conical and flat-bottom) and different edge conditions (sheared and machined) to understand the effects of testing conditions on performance, and these results are discussed in terms of mechanical properties and microstructures.

Experimental investigations of the in-die quenching efficiency and die surface temperature of hot stamping aluminium alloys

Abstract: The in-die quenching is a key stage in the hot stamping volume production chain which determines the post-formed strength of lightweight alloy components, tool life, and hot stamping productivity. In this paper, the performance of in-die quenching, reflected by the quenching efficiency (the time of work-piece held within stamping dies) and die surface temperature during the simulated hot stamping process of AA6082, was experimentally and analytically investigated. A range of in-die quenching experiments were performed for different initial work-piece and die temperatures, quenching pressures, work-piece thickness, and die clearances, under hot stamping conditions. In addition, a one-dimensional (1D) closed-form heat transfer model was used to calculate the die surface temperature evolution that is difficult to obtain during practical manufacture situations. The results have shown that the in-die quenching efficiency can be significantly increased by decreasing the initial work-piece and die temperatures. Die clearances are required to be designed precisely to obtain sufficiently high quenching rates and satisfying post-formed strength for hot-stamped panel components. This study systematically considered an extensive variety of influencing factors on the in-die quenching performance, which can provide practical guides for stamping tool designers and manufacture systems for hot-stamping volume production.

Parametric study and design of deep learning on leveling system for smart manufacturing

Abstract: Sheet metal is widely used in the industry for metal forming purposes, such as metal stamping and metal cutting. It is often winded and storage in a coil form for transportation purposes. However, before any manufacturing process such as, cutting, or stamping, leveling is required as the residual stress inside coil is present which can cause distortion to the metal forming/cutting process. In conventional coil leveling machines, the machine parameters are often set by machine technicians with many years of experiences. In addition, the optimized machine parameter is achieved by trial and error method or based on experiences. However, the machine parameters are also not exactly trivial due to too many input factors which may cause changes to the outcome result. In the recent years, industry 4.0 and smart manufacturing has been a widely discussed topic in terms of industry manufacturing solutions in many different industrialized countries. In smart manufacturing, communication and interaction between machines have become an important role to improve manufacturing efficiency, flexibility and customization. As smart manufacturing focused on information process through real objects, it is required to digitize the experience through deep learning method. This paper is aimed to describe and study the deep learning application based on coil leveling system. Finally, through this study and experiment verification, analyzes on research directions and prospects of deep learning.

Электропластический эффект в металлах

Abstract: A mechanism of electroplastic effect considered as well as possible areas of its technological application during rolling, drawing, stamping of thin sheets and other methods of metals forming. A conception justified that metal electroplastic deformation, based on electroplastic effect, can be applied at middle and final metallurgical stage. Electroplastic effect allows to decrease metal resistance to deformation by 25–30% and increase the ductility of a metal during its forming, to increase residual ductility till 30%. Due to increasing of axial texture perfection degree of wire during drawing technology with electroplastic effect application, a decrease of its electric resistance by 15% is reached. During the metal electroplastic deformation of stainless steels the austenite-martensitic phase γ→α transformation is practically completely suppressed, which makes unnecessary operations of money-and energy consuming austenizating annealing. Based on electroplastic effect about 45 mills and powerful metal-processing facilities, using metal electroplastic effect deformation created in different countries (mainly in Russia, South Korea, Italy, Great Britain and China). Different variants of effective energy-saving critical technologies are being developed by metal electroplastic effect deformation by rolling, drawing, stamping and flatting, as well as briquetting of metal wastes with current. A new equipment is created and existing equipment is modernized for application of metal еlectroplastic effect deformation technology.
