这项研究的目的是通过实验观察 在超塑性过程中的非均匀流动过程 变形，并研究它们与宏观的关系 本构响应通过有限元建模的 微观结构 重点将放在实验上 分离操作位错和扩散流动过程 以及检测单个内的变形的不均匀性， 以及更大的谷物集合中。

The objective of the proposed research is to experimentally observe the inhomogeneous flow processes operative during superplastic deformation and to study their relationship to the macroscopic constitutive response through finite element modeling of the microstructure. Emphasis will be placed on experimentally isolating the operative dislocation and diffusional flow processes and the detecting the inhomogeneity of deformation within single grains as well as within larger collections of grains.
