Abstract
Superplastic flow in fine-grained materials takes place mainly by grain boundary sliding. Micrograin superplasticity has been discussed mainly from the analysis of flow stress against strain rate relationship to find an accommodation process for grain boundary sliding. The phenomenological analysis has commonly been used to make clear the general features on micrograin superplasticity and will also be a major approach for superplasticity research in the future. However, some experimental facts reported in recent years, particularly in ceramic materials, cannot be understood from this type of analysis. This paper aims to show that microscopic analysis on grain boundary structure, chemistry and local atomic bonding state is very effective to break through the limitation of phenomenological approach.
