“…Soundararajan et al confirmed that the improved wear resistance of A356/fly ash AMCs was due to increased bonding of the fly ash particles with the A356 aluminum alloy [30]. Reddy et al highlighted that through the addition of fly ash to Al 2 O 3 -reinforced AMCs, there was a reduction in the weight as well as in the cost of the AMCs [31].…”

In the present work, a metal–matrix composite was casted using the LM13 aluminum alloy, which is most widely used for casting automotive components. Such applications require materials to withstand high operating temperatures and perform reliably without compromising their properties. In this regard, particulate-reinforced composites have gained widespread adaptability. The particulate reinforcements used comprise of one of the widely available industrial by-products. which is fly ash, along with the abundantly available quartz. Hybrid composites are fabricated through the economical liquid route that is widely used in mass production. Though there are numerous published research articles investigating the mechanical properties of metal–matrix composites, very few investigated the thermal properties of the composites. In the present work, thermal properties such as thermal conductivity and thermal diffusivity of cast hybrid composites were evaluated. The particulate reinforcements were added in varied weight percentages to the molten LM13 alloy and were dispersed uniformly using a power-driven stirrer. The melt with the dispersed particulate reinforcements was then poured into a thoroughly dried sand mold, and the melt was allowed to solidify. The quality of the castings was ascertained through density evaluation followed by a microstructural examination. It was found that the composites with only the fly ash particles as a reinforcement were less dense in comparison to the composites cast with the quartz particulate reinforcement. However, the hybrid composite, with both particulate reinforcements were dense. The microstructure revealed a refined grain structure. The thermal diffusivity and thermal conductivity values were lower for the composites cast with only the fly ash reinforcement. On the other hand, the composites cast with only quartz as the particulate reinforcement exhibited higher thermal diffusivity and thermal conductivity. The specific heat capacity was found to be lower for the fly ash-reinforced composites and higher for the quartz-reinforced composites in comparison to the LM13 base matrix alloy. However, the highest value of thermal diffusivity and thermal conductivity were reported for the hybrid composites with a 10 wt.% inclusion of both fly ash and quartz particulate reinforcements.

<div>Recent developments in manufacturing techniques and the development of Al7075 metal matrix composites (MMCs) with reinforcements derived from industrial waste have been steadily gaining popularity for aerospace and automobile applications due to their outstanding properties. However, there are still a lot of limitations with these composite materials. A great deal of research has been done to create new Al7075 MMC materials with the use of economic fly ash (FA) that possesses superior mechanical properties, corrosion resistance, density, and cycle cost. This review outlines different synthesis techniques used in the development of Al7075 MMCs using stir casting. Effects of FA along with other reinforcements on the mechanical, wear, machining, and microstructural properties of the composite are also discussed. Finally, a summary of the application of FA-based MMCs and a recap of the previous discoveries and challenges are reported. Future scope and potential areas of application are also discussed. This will inspire the potential researchers to understand the benefits of using FA as a reinforcement and carry out researches on this area that will be beneficial for the society economically as well as environmentally.</div>
