Abstract Carbide precipitation plays a key role in determining mechanical properties of Co-Cr-Mo alloy. Precipitation characteristics of carbides in selective electron beam melting (SEBM)-fabricated Co-Cr-Mo parts have been investigated by atom probe tomography and transmission electron microscopy. We observe co-existence of two types of carbides, i.e. M 23 C 6 and M 6 C, which are formed into continuous carbide thin films along columnar grain boundaries. The carbide thin film is found to precipitate coherently with one γ Co grain while incoherently with another adjacent one. Moreover, columnar carbide chains or clusters consisting of nanometer-sized, cuboidal particles are precipitated coherently with surrounding γ Co phase within interdendritic regions.
