Abstract

Silicon carbide has gathered widespread attention as a potential reinforcement for aluminum matrix composites (AMCs) to enhance the properties and reduce the cost of production. Aluminum alloy 7075 reinforced with various amounts (5, 8 and 10 %) of silicon carbide particles were prepared by stir casting method. Silicon carbide particles were incorporated into the semisolid aluminum melt. The microstructures of the MMCs were analyzed using scanning micro electron microscopy. The MMCs were characterized with the homogeneous dispersion of silicon carbide particles having clear interface and good bounding to the aluminum matrix. The incorporation of silicon carbide particles improved the micro-hardness and ultimate tensile strength (UTS) of the MMCs.
