Abstract This study investigated the effects of dislocation patterns introduced by cold rolling deformation on the hydrogen absorption properties, hydrogen trap behaviors and hydrogen embrittlement (HE) resistance for Armco iron under electrochemical charging. The surface hydrogen coverage first increases and then decreases with increasing deformation, and reaches a maximum at 50% deformation. Dislocation cell walls appear when the deformation is greater than 50%. Furthermore, the HE resistance is improved when the deformation reaches 80%. Because the dislocation cell walls can be used as effective hydrogen traps when the dislocation density reaches a sufficiently high value.

位错胞壁对氢吸附、氢俘获和抗氢脆性的影响

摘要 本研究研究了冷轧变形引入的位错模式对电化学充电下 Armco 铁的吸氢性能、氢陷阱行为和抗氢脆 (HE) 性能的影响。表面氢覆盖率随着变形的增加先增加然后减少，并在50％变形时达到最大值。当变形大于 50% 时出现位错胞壁。此外，当变形达到80%时，抗HE性能得到提高。因为当位错密度达到足够高的值时，位错单元壁可以用作有效的氢陷阱。
