主　　题：NiMo Composites Fabricated by Hot Pressing Microstructure and Mechanical Properties of TiB2 Ni+Mo TiB 

摘      要：The fabrication of TiB2 ceramics with high performance at a relatively low temperature requires a second phase to assist the densification and control the microstructure. Moreover the interface characteristics of composites must also be considered. Nickel was chosen as a good metallic-bearing additive in this study. In order to optimize the interface, Mo was added. The results show that Mo can affect the interaction between TiB2 and Ni, and metallic liquid plays an important role in limiting the TiB2 grain growth in sintering.
