晶界滑动
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.
晶内位错滑移和扩散蠕变作为重要的协调机制,促进了晶界滑动的顺利进行.该合金的超塑性变形机制符合位错协调晶界滑动模型。
