Abstract

The effect of heat treatment on microstructure has been studied in a Co-Cr-Mo-C alloy using transmission electron microscopy. Isothermal aging treatments at 750 °C were found to promote a two stage fcc → hcp transformation, coincident with a discontinuous precipitation of M23C6 carbides. The variation in morphology of the carbides associated with the fcc → hcp transition is discussed in terms of the nature of the fcc/hcp interface.
