Summary

The U. S. Bureau of Mines is investigating composites in the system TiN/Al2O3/AlN as potential substitutes for critical and strategic materials. Electrical and physical property data, including oxidation resistance, hardness, strength, and fracture toughness of a titanium-aluminum-oxynitride (TiAlON)/aluminum oxynitride spinel composite are presented. The relationship between material properties, composition, phases, and processing parameters is discussed. The effects of additives such as yttria, lanthana, and ceria will also be presented. TiAlON/spinel composites exhibit variable strength and electrical resistivity dependent on composition.
