The superplastic flow with a maximum elongation of 256% and strain rate sensitivity of 0.3 to 0.7 were observed at temperature range from 900 to 1100℃ and initial rate 2.1 ×10-4 s-1. As combined with optical and TEM observations, it is suggested that a continuous recovery and recrystallization process took place and superplasticity may arise from this process.
