摘要
用电化学渗透法研究了拉伸形变对６５Ｍｎ钢三种组织珠光体、球化珠光体、回火索氏体的氢扩散系数和陷阱参数的影响．结果表明，扩散系数在开始形变时有一陡降，然后基本上随形变量呈直线下降，并在一定形变量（５～６％）后基本上保持不变．测得预充氢和不预充氢形变的陷阱能分别为５８～６４ＫＪ／ｍｏｌ和３０～３８ＫＪ／ｍｏｌ．
The effect of deformation on hydrogen permeation and trapping in 65Mn steel was investigated. The trapping energy of deformation ranged from 30 to 38(KJ/mol). The trapping energy of deformation ranged from 58 to 64 (KJ/mol) after charging hydrogen.
