Interfacial reaction and mass transport of the components in the Al2O3-TiN system during sintering

Conclusions Results of x-ray phase analyses have shown that Al₂O₃-TiN composites produced by nitrogen and vacuum heat treatment and hot pressing retain a two-phase structure at temperatures of up to 2300°K. The changes exhibited by the Al₂O₃ and TiN lattice parameters may be indicative of oxidation and subsequent dissolution of the resultant titanium oxides both in alumina and in titanium nitride. The extent of this reaction depends on the method and conditions of heat treatment.Translated from Poroshkovaya Metallurgiya, No. 11(275), pp. 32–38, November, 1985.
