Microstructure examination of cast Co-Cr-Mo alloy is presented in this paper. The surface morphology and chemical composition of alloy were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDX), respectively. The alloy phases identification was carried out by electron backscatter diffraction (EBSD).The different kinds of precipitates in non-homogeneous 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 valuable, supplementary method for materials research.
