STUDY OF PHYSICAL PROPERTIES OF TiC–NiCr CERMET COMPACTS OBTAINED BY HOT PRESSING

Abstract Results of an experimental study of physical properties, microstructure, and phase composition of a TiC–NiCr cermet compact obtained by hot pressing are presented. It is shown that an increase in the volume fraction of carbide inclusions is accompanied by an increase in hardness HRA (from 25 to 55) and microhardness HV300 (from 350 to 1000) of the material.
