Abstract: The metal matrix composites offers 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 mechanical properties of Silicon Carbide particulate (SiCp) reinforced Aluminum matrix composite after retrogression and re-aging. Aluminum 7075 alloy with 10%, 15% and 20% SiCp were studied.

Keywords: Retrogression and Re-aging, Aluminum 7075 alloy, heat treatment.
