中文摘要：
采用超重力下燃烧合成工艺，以快速凝固方式制备出TiB2系列含量的TiC-TiB2细晶复合陶瓷。XRD、FESEM与EDS分析表明，随TiBz含量的增加，TiC-TiBz复合陶瓷基体从TiC微米球晶组织逐渐转化为TiB。小尺寸片晶组织，且对于TiBz含量为50％的TiC-TiBz复合陶瓷，可获得TiB2小尺寸片晶均匀镶嵌于TiC基体上的共晶组织。力学性能测试结果表明，TiBz的摩尔分数为50％的TiC-TiB2复合陶瓷因在凝固过程中发生共晶反应，陶瓷相对密度和硬度均达到最高值（分别为98．6％和18．4GPa），并且因TiBz小尺寸片晶在裂纹扩展时所诱发的裂纹偏转、桥接及片晶拔出增韧机制的协同作用，TiB。的含量为66．7％的TiC-TiB。复合陶瓷具有最高的断裂韧度（13.4MPa·m^0.5）。
