摘要：

Silicon nitride (Si3N4) ceramics incorporated various amount of titanium diboride (TiB2) were fabricated by hot pressing at 1800 degreesC for 1 h. The influence of TiE2 on the microstructure and mechanical properties Of Si3N4 ceramic was investigated. When a small amount of TiB2 (2 vol.%) was added, the mechanical properties of Si3N4 were improved significantly, whereas they began to degrade when more TiB2 (greater than or equal to 4 vol.%) was introduced. The reaction between TiE2 and Si3N4 matrix is responsible for the variation in mechanical properties of the TiB2/Si3N4 composites. (C) 2004 Elsevier B.V. All rights reserved.
