Abstract

Intergranular boundaries, structures and phases are key microstructural components in advanced ceramic materials where dopants often play a leading role. This extended abstract summarizes the observations and analyses of the chemistry and structural evolutions that take place at intergranular boundaries and pockets during high-temperature deformation processes in Si-based ceramics. Quantitative analysis of these intergranular structures by analytical transmission electron microscopy is proved very important here to understand the dynamic development of the microstructure, which can shed light into the mechanism for plasticity and creep behaviors in high temperature structural ceramics such as SiC and Si3N4.

Keywords: AEM; Intergranular phase; Superplasticity; High temperature creep; SiC; Si3N4
