摘要: 本文作者就慢应变速率拉伸条件下工业纯铁试样的氢渗透进行了研究,并将片状,棒状试样的不同实验方法加以比较。结果表明:片状与棒状试样的衰减曲线具有完全相同的规律。在拉伸条件下,表观扩散系数D被考虑为应变ε的函数,使用拟牛顿迭代法可求得非线性方程组的解,并因而可求得D值。

Abstract：Plate specimens of commercially pure iron and cylindrical specimens of low a11oy steel were tested for hydrogen permeation under slow strain rate tensile test condition. Results showed that J/J(?) versus time curves of the evolution of hydrogen for both plate and cylindrcal specimens were similar. Apparent diffusivity D as related to tension is considered as a function of strain from which a mathematical solution of D can be obtained by using Newton'S method to solve the groups of non-linear equations by means of computer.
