摘要：

Densification behaviour, microstructure and properties of TiN and TiB2-based composites were compared to monolithic materials. Improvements in sinterability and properties were obtained with the addition of nickel as sintering aid. In TiB2-based composites, the addition of B4C as second phase increased strength and toughness of about 22% and 25%, respectively. In TiN-based composites, the addition of TiB2 as reinforcing phase improved both hardness and strength in comparison to pure TiN ceramic. Sintering behaviour is discussed in terms of starting compositions; mechanical and physical properties are related to microstructural characteristics.
