A CERMET HAVING A BINDER WITH IMPROVED PLASTICITY, A METHOD FOR THE MANUFACTURE AND USE THEROF

摘要

Cermets having a Co-Ni-Fe-binder, a method for the manufacture and use there of are described. The Co-Ni-Fe-binder comprises about 40 wt.% to 90 wt.% Co, the remainder consisting of Ni, Fe and incident al impurities. The binder is unique in that even when subjected to plastic deformation, it substantially maintains its face center ed cubic crystal structure and avoids stress and/or strain induced phase transformations. Stated differently, the Co-Ni-Fe-binder exhibits reduced work hardening. The cermets are used as tools for mining and construction, for machining materials, and as a screw head punch.
