摘　　要：In the present investigation,composites with silicon carbide particle(SiCp) as reinforcement and AZ91magnesium alloy as matrix have been synthesized using liquid metal stir-casting technique with optimized processing conditions.The composites with good particle distribution in the matrix,and better grain refinement and good interfacial bonding between the matrix and reinforcement have been obtained.The effect of SiCpcontent on the physical,mechanical,and tribological properties of Mg-based metal matrix composite(MMC) is studied with respect to particle distribution,grain refinement,and particle/matrix interfacial reactions.The electrical conductivity,coefficient of thermal expansion,micro-as well as macro-hardness,tensile and compressive properties,and the fracture behavior of the composites along with dry sliding wear of the composites have been evaluated and compared with the base alloy. 关键词：金属基复合材料摩擦学性能物理搅拌机械 SIC颗粒 AZ91镁合金属性
