摘要：

The high strain rate superplasticity (HSRS) in a Ti-based alloy processed by high pressure torsion (HPT) straining was observed. Enhanced superplasticity in the alloy subjected to high pressure torsion associated with the formation of ultra-fine grains during heating after SPD-processing was found.
