MICROSTRUCTURE AND MECHANICAL PROPERTIES OF TiB_2-B_4C CERAMIC COMPOSITES
TiB2—B4C陶瓷复合材料的微观组织和机械性能

The fracture strength and hardness of TiB_2 materials increase by addi- tion of 20--30 wt-% B_4C and the fracture toughness still remains on the original high level. The mechanism of reinforcement and crack propagation have been discussed
