The dominant deformation mechanism is grain-boundary sliding.The dislocation sliding in grain and diffusion creep, as two kinds of important coordination mechanism,promote the development of grain-boundary sliding.The superplastic deformation mechanism accords with the model of dislocation coordinating grain-boundary sliding.
