| Abstract: | According to sintering theory, the distributing model of dispersion particle and the computing residual stress model were built, and residual stress was computed at one - dimension direction. The mechanics of dispersion SiC particle toughing alumina was researched in theory, and the influence factor of residual stress was analyzed. Therefore theoretical reference of how to choose SiC particle size and quantity was provided. |
