摘要

Polycrystalline materials having crystallographic anisotropy show internal stress superplasticity under thermal cycling conditions. The deformation mechanism is analyzed using a theoretical model based on continuum micromechaics including the effects of crystallograhpic texture. The model is experimentally verified through the thermal cycling creep tests using polycrystalline zine having two kinds of fiber-texture, and agrees well with the experimental results.
