Research the Preparation of SiC/AI Composites by High Energy Ball Milling

摘要

High energy ball milling was used to preparation SiC/AI composites flakes. The research found the milling parameter of high energy milling was the ball/powder ration is 20:1, the rotary speed is 800 r/min, the milling time is l00min.Also researched the molding process of SiC/AI composites, the change of grain size and the weight fraction of the SiC, The research also found the mechanical properties of SiC/AI composites affected by the molding process. It was found that to reduce particle size and increasing of weight fraction of SiC, tensile strength of the SiC/AI composites increased.
