An analysis has been made on the mechanical behavior of aluminum metal matrix composite reinforced with 10 wt% SiC and 2 wt % of TiO2. Stir casting route has been adopted to fabricate these composites. Different mechanical tests have been carried out on these MMC’s and base alloy, to study the mechanical properties. Furthermore, the effects of reinforced particles sizes on the microstructure of the composites were observed by using SEM. These MMCs are to be used for automobile, aircraft and space industries. Hence a solution is needed to solve the issues like selection of material on the basis their mechanical properties.
