Abstract

Cermets having a Co--Ni--Fe-binder are described. The Co--Ni--Fe-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic crystal structure and avoids stress and/or strain induced phase transformations. Stated differently, the Co--Ni--Fe-binder exhibits reduced work hardening.
