Interface Characterization of the SiCp/Al Composites Made by Powder Metallurgy

Abstract

Abstract: The interface of the SiCp/Al composites produced by powder metallurgy processing involving hot pressing above the matrix solidus temperature has been investigated by means of TEM. Several kinds of interfaces between the reinforcements and the matrix in the composite, including the clean interfaces, the faceted interfaces and the slight reaction interfaces, are presented. And most of interfaces belong to the slight reaction interfaces which are composed of the Al with different orientation from the Al matrix near the interface zone and particle-like substances produced by MgAl2O4 spinels and impurities.
