In recent days, the demand of light weight materials being increased in industrial applications especially nano composites are used in aerospace, automobiles and bio medical applications due to their favorable properties. The aluminium alloy matrix can be strengthened by reinforcing with hard ceramic particles. In this present investigation is focuses on characterization of metal matrix composites of Al6063 alloy reinforced with boron carbide nano-particles with varying weight percentages of 2, 4 and 6%, the Al 6063was choose as base material owing to its good formability lightweight and moderate strength The composites were fabricated by using stir casting techniques The fabricated composites were characterized using scanning electron microscope. The micro structural studies reveals that the uniform distribution of boron carbide nano-particles in the aluminium alloy matrix by showing good bonding with matrix and EDS confirmed the presence of Boron and Carbon elements. Mechanical properties have been studied for the composite samples. It was observed that the mechanical properties like yield strength, ultimate tensile strength, and hardness were improved by the addition of the B4C nano –particulates compared with the base metal.
