摘要：
The extraordinarily large superplastic elongation depends on the ability of fine grains to maintain an equiaxed shape during deformation without fracture. Grain switching is the topological principle of superplasticity. In three dimensions the face-creation switching and face-elimination switching are elemental processes not only in superplasticity, but also in the evolutionary formation of grain boundary networks in grain growth and sintering.
