EBSP study of reaction zone in SiC/Al metal matrix composite prepared by laser melt injection

摘要

The reaction zone in SiC/Al metal matrix composite layer prepared by Laser Melt Injection process is studied by Electron Back-Scatter Diffraction. Special attention is dedicated to the sample preparation process and also to the automatic indexing procedure when patterns of back-scattered electrons are evaluated during the surface scanning by electron beam. The orientation relationship between ceramic particles and phase formed in the reaction zone was observed by both transmission electron microscopy and by EBSD.
