“…Malaki et al reported that the inclusion of nano SiO 2 particles improved AMCs' tensile and compressive strength [27]. Tirfe et al prepared Al6061/Al 2 O 3 /quartz hybrid AMCs and concluded that the hardness, compressive and impact strength of the AMCs improved with the addition of the optimum content of quartz particles [28]. Fly ash, a type of industrial waste, is yet another promising reinforcing material that has found increased usage to reinforce AMCs in recent years.…”

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.

The quantum of work with silicon carbide (SiC) and zirconium dioxide (ZrO2) in the aluminum hybrid composite material has increased due to the growing demand for lightweight materials for various industrial applications. The aluminum hybrid composite with the wt% of primary reinforcement particles of SiC was kept constant at 5%, and the secondary reinforcement particles of ZrO2 were taken by 5%, 10%, and 15%. The sintering parameters were used as the temperature at 600°C, holding time of 35 minutes, and pressure at 30MPa. In this work, the aluminum composite material reinforced with 5%wt of SiC particles compared the test results with aluminum hybrid composite reinforcement of SiC and ZrO2 nanoparticles. Adding ZrO2 reinforcements enhances the aluminum hybrid composite material's better microstructure, microhardness, tensile strength, compression, and yield strength.
