In this paper microstructure and mechanical properties of Mg/SiC metal matrix composites produced by stir casting down pouring technique were investigated. Magnesium composites reinforced with 1, 3, 6, 9 and 12 wt. % SiC were produced by stir casting route. The microstructure of as-cast composites was studied by using optical microscope and scanning electron microscope (SEM). The grain size of magnesium metal matrix composite was much smaller as compare to pure magnesium. The mechanical properties of composites were better than monolithic magnesium which were attributed to refined grain size and presence of hard SiC particles. The best results for hardness and tensile strength were obtained with 9% SiC reinforcement. The fracture mechanisms of tensile samples were evaluated by using SEM images.
