A validated thermal model of bead-on-plate welding
TL;DR: In this paper, a finite element model is used to carry out thermal analysis of bead-on-plate welding and the model followed the proposed five step strategies which were then built into a model to obtain temperature history at the positions of thermocouples.
Journal ArticleDOI
Microstructural and Electrochemical Evaluation of Fusion Welded Low-Nickel and 304 SS at Different Heat Input
TL;DR: In this paper, the effect of heat input using E 308 electrode (controlled by welding current, i.e., 70, 85 and 100 A) on microstructure, mechanical properties and corrosion behavior of low-nickel and 304 stainless steel (SS) weldments produced by shielded metal arc welding technique was investigated.
Journal ArticleDOI
Effects of post-processing on the thermomechanical fatigue properties of laser modified NiTi
TL;DR: In this article, the effects of thermomechanical treatment on laser modified NiTi wires, while comparing them to the original base material, were investigated using a scanning electron microscope (SEM) and transmission electron microscopy (TEM).
Journal ArticleDOI
Study of the Direct Metal Deposition of AA2024 by ElectroSpark for Coating and Reparation Scopes
TL;DR: In this article, the authors used ElectroSpark Deposition (ESD) to fabricate a 2024 aluminum alloy deposit on a similar substrate, which was characterized by the overlapping of layers with a mixed microstructure.
BookDOI
Cracking Phenomena in Welds IV
TL;DR: The fourth volume in the well-established series of compendiums devoted to the subject of weld hot cracking as discussed by the authors contains the papers presented at the 4th International Hot Cracking Workshop held in Berlin in 2014.

Journal ArticleDOI
A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties
TL;DR: In this article, the state of the art in selective laser sintering/melting (SLS/SLM) processing of aluminium powders is reviewed from different perspectives, including powder metallurgy (P/M), pulsed electric current (PECS), and laser welding of aluminium alloys.
Journal ArticleDOI
Dislocation network in additive manufactured steel breaks strength–ductility trade-off
Leifeng Liu,Qingqing Ding,Yuan Zhong,Ji Zou,Jing Wu,Yu-Lung Chiu,Jixue Li,Ze Zhang,Qian Yu,Zhijian Shen +9 more
TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.
Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
Revisiting fundamental welding concepts to improve additive manufacturing: From theory to practice
TL;DR: In this article, a unified equation to compute the energy density is proposed to compare works performed with distinct equipment and experimental conditions, covering the major process parameters: power, travel speed, heat source dimension, hatch distance, deposited layer thickness and material grain size.
Journal ArticleDOI
Using deep neural network with small dataset to predict material defects
TL;DR: This study attempted to predict solidification defects by DNN regression with a small dataset that contains 487 data points and found that a pre-trained and fine-tuned DNN shows better generalization performance over shallow neural network, support vector machine, and DNN trained by conventional methods.
