Abstract
This paper presents the results of an experimental study of the physical properties, microstructure, and phase composition of a TiC-NiCr ceramic-metallic compact obtained by hot pressing. It is shown that an increase in the volume fraction of the metal binder in the samples reduces the HRA hardness (from 55 to 25) and the HV300 microhardness (from 1000 to 350) of the material.
