摘要

Effects of the body centered cubic distribution of the dispersed SiC and (W,Ti)C particles on the residual thermal stresses of (W,Ti)C/SiC/Al_2O_3 ceramic composite were analyzed with the finite element method, especially with the comparison with that of the face centered cubic distribution. Results show that the residual thermal stress is affected not only by each material compositions but also by the distribution forms of the dispersed SiC and (W,Ti)C particulates. Both distribution and magnitude of residual thermal stress differs with the difference in the particle distribution forms. The calculation results of different particle drnistribution forms, however, are just the reflection of different cases of the residual thermal stresses inside the ceramic composite from different points of view. Both reflections can research agreement in trends.
