Abstract

In this work, advanced capabilities of electron backscatter diffraction (EBSD) were applied to evaluate the role played dynamic recrystallization during superplastic deformation of a typical fine-grained material. It was found that the dynamic recrystallization occurred only locally and thus provided only minor contribution to microstructural evolution. Hence, the preservation of the nearly-equiaxed grain morphology, inherent to the superplasticity phenomenon, cannot be attributed to the dynamic recrystallization.
