In the present study, magnesium RZ5 alloy based metal matrix composites have been developed using stir casting route, with B4C powder as reinforcement. Microstructural study of the base alloy and the composites have been carried out using field emission scanning electron microscope. Energy dispersive x-ray spectroscopy was conducted to know the presence of different elements. The effects of reinforcement on the mechanical properties of the composites were investigated by taking 2, 4 and 6 wt. % of B4C powder. Significant improvement in hardness, yield strength and ultimate tensile strength was observed in the composite compared to the base alloy. The hardness of the composite was found to be 124 VHN for reinforcement of 6 wt. % of B4C, for the base alloy hardness value was 72 VHN. Ultimate tensile strength of the material increased from 145 MPa to 169 MPa as a result of B4C reinforcement.
