Silicon Carbide Particle Reinforced Aluminum Matrix Composite Prepared by Stir-Casting.

The developed aluminum matrix composite (AMCs) is considered to be a promising material for low and high temperature applications. Particles reinforced AMCs materials have high specific strength and modulus of elasticity, together with excellent heat resistance. Silicon carbide particles reinforced aluminum matrix composite (AMCs) for hardness, impact strength, and material toughness improvement were prepared. Stir-casting processing was optimized. The hardness, impact strength, and material toughness were evaluated. Under stir-casting, the silicon carbide particles were uniformly distributed in the aluminum and well bonded with aluminum matrix. The hardness and material toughness were increased 1.84 and 2.16 times respectively at particles weight fraction (10 % ) that of the of the unreinforced aluminum based on the high hardness and deformation resistance of the silicon carbide particles
