The sintering of powders with the object of obtaining titanium carbide-base hard metals is accompanied by chemical and structural transformations together with the evolution and absorption of heat. In this study the authors studied this process by means of thermal analysis. Results of this study show that exothermic effect in a thermal analysis of TiC-TiNi powder mixtures is due to oxidation of the titanium during heating in air, while heat absorption at temperatures below 1400°K is linked with contact melting.
