Abstract
3YSZ ceramic superplasticity has been investigated for many years, and the primary mechanism for superplastic deformation is grain boundary sliding. However, the accommodation mechanism for grain boundary sliding is controversial. In this paper, the 3YSZ ceramic was deformed in tension at different constant stress conditions. Superplastic deformation of 3YSZ ceramic was observed with the assistance of DC electric field. It indicated that at the high tensile stress condition, dislocation motion may play a role in the accommodation mechanism for grain boundary sliding.
