TL;DR: In this article, an attempt has been made to optimise the sintering process parameters of Al-Si alloy/fly ash composite using grey relational analysis, and the results indicate that multi-response characteristics such as density and hardness can be improved effectively through Grey relational analysis.
Abstract: In this paper, an attempt has been made to optimise the sintering process parameters of Al–Si (12%) alloy/fly ash composite using grey relational analysis. Al–Si alloy/fly ash composite was produced using powder metallurgy technique. Al–Si alloy powder was homogenously mixed with various weight percentages of fly ash (5–15 wt.%) and compacted at a pressure ranging from 307 to 512 MPa. The green compacts were sintered at temperatures between 575 and 625°C. Experiments have been performed under different conditions of temperature, fly ash content, and compacting pressure. Taguchi’s L9 orthogonal array was used to investigate the sintering process parameters. Optimal levels of parameters were identified using grey relational analysis, and significant parameter was determined by analysis of variance. Experimental results indicate that multi-response characteristics such as density and hardness can be improved effectively through grey relational analysis.

TL;DR: In this paper, the authors discussed the formulation of distinct hybrid laminates with various weight ratios of jute and linen-incorporated epoxy polymer and the influence of their weight ratios on the dynamic attributes.
Abstract: Owing to growing environmental awareness in green technology, the whole gamut of engineering sector has started shifting towards natural fibre-oriented materials from synthetic materials. The adequate dynamic stability and damping property are important design necessities in a polymer composite structure. Given this perspective, this paper discusses the formulation of distinct hybrid laminates with various weight ratios of jute- and linen-incorporated epoxy polymer and the influence of their weight ratios on the dynamic attributes. Dynamic mechanical thermal analysis is employed to quantify the viscoelastic attributes of the hybrid laminates. The natural frequency of cantilevered laminate beam is determined experimentally by free vibration analysis and the damping factor of the laminate beam is computed analytically by half power bandwidth technique. The cole–cole mapping analysis is made to understand the interfacial adhesion of the different laminates with hybrid configurations. The hybrid laminate with equal weight proportion of jute and linen is found to be optimal as it has exhibited maximum stiffness property and load bearing capability with high glass transition temperature. The influences of frequency on storage modulus and loss factor of the optimal hybrid laminate with respect to temperature are analysed. Several vibratory responses of the optimal hybrid laminate beam for different natural frequencies and damping factors are elicited and studied.

TL;DR: Aluminium (Al) silicon alloy fly ash composites were developed using powder metallurgy technique as mentioned in this paper, and various properties of the Al alloy fly-ash composites are studied and compared with that of base alloy.
Abstract: Aluminium (Al) silicon alloy fly ash composites were developed using powder metallurgy technique. Aluminium silicon alloy powder was homogenously mixed with various weight percentages of fly ash (5–15%) and uniaxially cold pressed at pressures ranging between 200 and 515 MPa, and the green specimens were sintered at temperatures between 575 and 625°C. The various properties of the Al alloy fly ash composites were studied and compared with that of base alloy. The density of Al alloy fly ash composites was lower than that of the base alloy. The sintered density of the Al alloy fly ash composites and Al alloy slightly decreased when compared to green density. The hardness of the Al alloy fly ash composites was higher than that of base alloy and it increased with the increase in weight percentage of fly ash content upto 12 wt-%. Compressive strength of the composites was lower than that of base alloy and it decreased with increasing weight percentage of fly ash. The electrical resistivity and corrosio...

TL;DR: In this paper, the authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal-matrix composites (MMCs), providing an insight into the challenges and opportunities for the exploitation to their full potential.
Abstract: In this contribution, authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal–matrix composites (MMCs), providing, through the judicious analysis of an ample and varied references source – from the oldest to the newest ones – an insight into the challenges and opportunities for the exploitation to their full potential. In addition to its topicality, the novelty of this contribution lies in the presentation of key statistical, technical, and property-related information of a comprehensive variety of waste materials classed into two main groups, namely, fly ash reinforced MMCs and MMCs derived from other waste materials. Although fly ash has been exploited in a broad range of applications, the attention paid for its use in the development of MMCs seems to be insufficient. A purposely designed chart helped to pinpoint the more demanding and profitable applications of fly ash, and establish strategic opportunity ar...

TL;DR: In this paper, the synthesis and characterization of hybrid aluminium matrix reinforced with micro SiC particles, and nanocopper oxide (CuO) particles prepared by sintering process is discussed.
Abstract: The application of nano-sized particles is increasing because it strengthens the Metal Matrix composites (MMCs) and maintains the ductility of the matrix alloy. The present investigation deals with the synthesis and characterization of hybrid aluminium matrix reinforced with micro SiC particles, and nanocopper oxide (CuO) particles prepared by sintering process. First the powder mixtures containing fixed weight (wt)% of SiC and different wt% of nanocopper oxide as reinforcement constituents that are uniaxially cold pressed. Afterwards the green compacts are sintered in an electric muffle furnace. Microstructure and mechanical properties such as tensile strength, microhardness and density of the composites are examined. Microstructure of the samples has been investigated by using scanning electron microscope (SEM), X-ray diffraction (XRD) and Atomic Force Microscope (AFM). The results indicated that the increase in weight% of nano Cuo particles improves the mechanical properties.
