Effect of Mixing Method on Microstructure of SiCp/Al Composites

Abstract:

The fine and homogenous distribution of the SiC particles in Al metal matrix is basic prerequisite for improving the properties of the SiCp/Al composites. In this paper, the effects of high energy ball milling and ordinary ball milling on the spatial distribution of reinforcement of the SiCp/Al composites have been investigated. The result showed that high energy ball milling is the most effective method to get homogeneous distribution of SiC particles in Al matrix. There were many clusters of SiC particles in the composites fabricated by ordinary ball milling.
