Abstract

Superplasticity is known as the ability to sustain a large deformation with its necking resistance under small stresses. The phenomena are now classified into two groups: ″microgrin superplasticity″ and ″dynamic superplasticity″ . In the former, behavior of micrograin superplastic deformation, a large amount of grain boundary sliding during the deformation, grain boundary migration, or grain rotation have been observed. In this paper, a new microscope has been specially developed to observe directly the deformation under high temperature conditions. Performance of the apparatus and some results from observations in pure iron are reported.
