Results are presented of a study dealing with an AlN–TiN composite material for high temperature applications. Hardness, microhardness, compressive strength, electrical resistance, and thermal conductivity of the material were measured at room temperature and flexural strength was measured at temperatures from 20 to 1800°C. The composite material containing 40 wt-% AlN and 60 wt-% TiN and hot pressed at 1850–1950°C exhibits an increase in strength of 20% with a rise in temperature, which permits it to be used at elevated temperatures.
