| Research Abstract |
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.
