Abstract

Metal matrix composites (MMC) are a new type of material that has the potential to be used in a wide range of applications, including aerospace, automotive, and mining. MMC are made by combining a metal matrix with a ceramic reinforcement material. Fly ash, a waste product from coal combustion. It is a fine-grained powder that is rich in silica and alumina. Fly ash has been shown to be a promising reinforcement material for aluminium metal matrix composite (MMC). However, the effect of fly ash content on the microstructure and mechanical properties of aluminium MMC processed by cooling slope casting is still unclear. This study will investigate the effect of adding fly ash to aluminium alloy MMC produced by cooling slope casting. The research will add 4, 8, and 12 weight percent fly ash to the aluminium alloy and then the aluminium alloy melts with fly ash, which is stirred at 350 rpm for 5 minutes and poured into the mold at a temperature of 800°C. Then, the specimen will be test for hardness, tensile strength, and density to investigate its characterization. It is expected that the addition of fly ash will improve the mechanical and physical properties of the aluminium alloy MMC. This is because fly ash particles can act as barriers to dislocation motion and refine the grain size of the aluminium matrix, both of which lead to an increase in strength. Additionally, fly ash is less dense than aluminium, so adding fly ash to the MMC could reduce their overall weight. The results of this study could lead to the development of new and improved MMC for a variety of applications.
