Boron carbide is one of such additions to aluminium which has made the application more vibrant due to its excellent combination of hardness and wear resistant properties. The size and distribution of these boron carbide are expected to control the mechanical and wear properties. Present work aims to understand the effect of size of boron carbide particles on the morphology and hardness in aluminum The present study involves aluminum alloy LM27 due to its stratagic applications in defence. Stir casting process has been used to fabricate the composite. The composites fabricated by varying the amount and size of boron carbide particles. Microstructural study has been undertaken by using optical microscope. Boron carbide particles of size ranging 20-100 μm has been used in the present study. Micro hardness and bulk hardness measurement has also been undertaken for developed composites.
