Aim of this project work is to synthesize Al7075/B4C/Gr composite material using the Stir Casting process and to test the Mechanical properties by ASTM E8M-15a, ASTM D695, IS 1500-2010, ASTM G99 and SEM and EDAX images are used for morphological characterization. In last 10 years many researchers have investigated Aluminium Matrix composite with SiC, Grey cast iron, TiB, Al2O3, ceramic, copper, TiC, Mg etc.…, still many works are ongoing with varying % of reinforcement to attain the increasing demand for Automobile and marine applications. Despite B4C having lower density, good wettability, significant thermal stability, and outstanding chemical inertness very few works are there using B4C as a reinforcement agent. In the present study an effort has been made to synthesize B4C and Gr reinforced Al7075 hybrid composite using stir casting method by varying weight percentage (0%, 1.5%, 3% and 4.5%) of B4C and keeping the (1%) of Gr constant. Results from Tensile, compression, BHN shows there is increase in Brinell Hardness Number, Compression strength and Ultimate tensile strength of the composite respectively with varying percentage of Boron carbide and from wear test results it is observed that resistance to wear increases as the percentage of reinforcement increases gradually.
