Summary

Compositions in the TiN-AlN-Al203 phase diagram are being investigated by the Tuscaloosa Research Center of the U.S. Bureau of Mines for potential use in severe service conditions. Powder mixtures were prepared for evaluation by pressureless sintering in N2 at 1850° C for 2 hours or by hot pressing under 27.6 MPa for 30 min. TiN content of the mixtures varied from 20 to 80 wt % while maintaining an equal weight ratio of A1N to A1203. Phases present after densification include TiN, A10N (spinel and polytypes) and AlN. The effect of the composition and processing parameters on density, porosity, tnicrostructure, electrical resistivity, and flexure strength (room temperature through 1000° C) will be discussed.
