Abstract

The present invention relates to a pulverulent material for the production of standardized TZM parts by sintering techniques, as well as the notion of using pulverulent nitridic or carbonitridic hard materials as alloying components in the production of the abovementioned alloy by melt-metallurgical processes (electron beam melting, arc melting).
