HEAT RESISTANCE OF TITANIUM-TUNGSTEN SINTERED CARBIDES

The article presents the results of tests of titanium-tungsten sintered carbides under thermal shock. It was established that for the alloy T15K6 the critical temperature of thermal shock, characterizing the heat resistance of the material, is 400°C, and for the alloy T5K10 it is 500°C. We investigated the regularity of change of the statistical characteristics of the results of experiments for determining the residual strength of sintered carbides at different temperatures of thermal shock. It was established that with increasing content of binder phase the nature of the resistance of materials to thermal stresses changes.
