Results showed that the flexural strength,hardness and fracture toughness were increased for Al2O3 ceramic with the additions of TiB2.Further improvement in frac-ture toughness can be obtained for Al2O3/TiB2 ceramic with the additions of SiC whisker.

• 而TiB2颗粒和SiC晶项协同对Al2O3进行增韧补强可使其断裂韧性显著提高。 Al2O3/TiB2陶瓷材料的主要增韧机理有；
