Abstract: Dense TiC-Al2O3 composites were produced by self-propergating high temperature synthsis and pseudo-hot isostatic pressing(SHS/PHIP). The composition, microstructure and properties of the product were analyzed. The results show that the product consists of quasi-spherical TiC and irregular Al2O3. The interfacial bonding between TiC and Al2O3 is smooth. Transverse rupture strength and hardness of TiC-Al2O3 composites are aproximately 510MPa and 17.8GPa.

Key words: SHS, PHIP, TiC-Al2O3, composites
