本文通过自蔓延高温合成结合准热等静压法（SHS／PHIP）制备出了致密度为97.2％的TiC-A12O3复合陶瓷．分析了合成产物的结构、组织和性能．结果表明，复合陶瓷由近乎球形的TiC颗粒和不规则的Al2O3相组成，TiC与Al2O3之间的界面光滑．TiC－Al2O3复合陶瓷的抗弯强度和硬度分别为510MPa和17.8GPa。
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.
