Metal Matrix Micro Composites (MMMCs), with the addition of micro-particulate reinforcements, can be significant for automobile, aerospace and numerous applications due to their low density and good mechanical properties, better corrosion and wear resistance, and low coefficient of thermal expansion compared to conventional materials. Designing the metal matrix composite material aims to combine the desirable attributes of metals and ceramics. The present work is focused on studying the mechanical properties of Aluminium alloy (7075) with Al2O3 and B4C micro-composite produced by the Stir Casting method. Different % age of reinforcement is used. The Stir casting technique is used to achieve a uniform dispersion of micro-particulate Al2O3 and B4C in molten aluminium alloy. A tensile test, Hardness test, and Impact test were performed on the samples obtained by the fabrication processes. A microstructural study will be carried out through an optical Microscope to know the distribution of Al2O3 and B4C micro particulates in Al alloy.
