Materials Design of Ceramics Towards Secure Materials

从微观结构的角度分析了烧结过程中的宏观收缩，以开发出组织均匀、无缺陷的“安全材料”。研究了两相复合材料烧结的微观模型，烧结过程中晶界和表面的相互作用对晶粒长大和粗化的影响，各向异性烧结应力，各向异性收缩率和粘度，以及晶界滑动对约束烧结和共烧结的影响。

The macroscopic shrinkage in sintering process was analyzed from the knowledge of microstructure, in order to develop "secure materials" that have uniform microstructure without defects. We investigated the microscopic model of sintering of two-phase composite, the interaction of grain boundary and surface in coarsening and grain growth during sintering, anisotropic sintering stress, anisotropic shrinkage and viscosity, and the effect of grain boundary sliding on constrained sintering and co-sintering.
