Particle reinforced aluminum matrix composites (PRAMMCs)show many excellent characteristics such as low coefficient of expansion,high strength,good wear resistance and good thermal stability ratio, and the preparation process is relatively simple, processing technology is more mature, more affordable. It is almost as close to net-shape materials. There has a fast development and application in the high-tech field of aerospace, automotive, and electronics. In this paper SiC PRAMMCs were prepared by the tradi...
