Abstract
Microstructure examination of cast Co–Cr–Mo alloy is presented in this paper. The surface morphology and chemical composition of the alloy were investigated by means of scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDX). An identification of alloy phases was carried out using electron backscatter diffraction (EBSD).Two different kinds of precipitates in metallic matrix were found. They were identified as MC and M23C6 type of carbides in Co-lattice solid solution.The advantages and limits of the EBSD method are described. It is presented that EBSD, as excellent tool for phase identification, is a valuable supplementary method for materials research.
