New metastable carbides produced by crystallization of amorphous CrC alloys

Abstract

The crystallization of carbon-rich CrC amorphous alloys allows new metastable chromium carbides to be produced. The structures of these carbides, which are strongly faulted, offer to the carbon atoms prismatic interstices, octahedral interstices, or both. These results suggest that according to the carbon content, more than one type of local order exists in the amorphous state for this metal-metalloïd system. © 1991.
