Abstract—The metal matrix composites offer a spectrum of advantages that are important for their selection and use as structural materials. A few such advantages are high strength, high elastic modulus, high toughness and impact resistance, low sensitivity to changes in temperature or thermal shock, high surface durability, low sensitivity to surface flaws, high electrical and thermal conductivity, minimum exposure to the potential problem of moisture absorption resulting in environmental degradation and improved machinability with conventional metal working equipment. The aim of the present study is to investigate the corrosion properties of Silicon Carbide particles (SiCp) reinforced Aluminum matrix composite after retrogression and re-aging heat treatment. Aluminum 7075 alloy with 0%, 10%, 20% and 30% SiCp were studied.
