Abstract
Superplastic deformation (SPD) of polycrystalline materials including metals and ceramics take place via the grain-boundary sliding (GBS) process. To scrutinize the deformation process and mechanism of this grain-boundary sliding in SPD is important for developing new type of high-strain rate superplastic materials. In this study, the dynamic viscoelastic experiments under tensile elongation for LAS glass ceramics were conducted for various superplastic strains.
