ABSTRACT
Particulate reinforced metal matrix composites (MMCs) are potential materials for a variety of applications due to their beneficial of physical and mechanical properties. The objective of this experimental investigation is to manufacture mono metal matrix composites (MMMC) and hybrid metal matrix composites (HMMC) using aluminium A356 as matrix alloy and SiC and Al2O3 is used as reinforcement particle with changing the wt. % of the reinforcement particle. Composites are fabricated by stir casting method. The results shows that the composite materials revealed better mechanical and physical properties, like hardness, high ultimate tensile strength, wear properties, high impact strength. It has been found that with increase in the wt. % of the reinforce particle wear resistance, hardness and tensile strength of hybrid MMC improved than the unreinforced A356 and mono MMC.
