Microstructural characterization of as-cast biocompatible Co-Cr-Mo alloys

►The solidification microstructure of an ASTM-F75 type alloy were studied. ►The alloys were poured under an industrial environment. ►Carbides and sigma phase identified by color metallography and scanning microscopy (SEM and EDS). ►Two carbide morphologies were detected “blocky type” and “pearlite type”. ►Minority phases were also detected.
