本文分析了由于温度的波动及初始晶粒尺寸差异对超塑性拉伸过程的影响。结果表明,它们对产生试样的不均匀变形都有重要的作用。并且能够将初始晶粒尺寸不均匀性和试样初始几何不均匀性在形式上统一起来。
This paper analyzes the influence of temperature fluctuations and initial grain size differences on the superplastic stretching process. The results show that they have an important effect on the non-uniform deformation of the sample. And can formally unify the initial grain size inhomogeneity and initial geometric inhomogeneity of the specimen.
