Abstract As a response to a comment by Gavriljuk and Teus, we discuss the effects of hydrogen-charging-induced crack formation and plastic deformation on a high hydrogen flux along the grain boundaries in pure iron. Because no cracks were observed in the microstructure of the pure iron specimen used in our study, the effects of crack formation could be ruled out. In contrast, dislocation localization near grain boundaries was observed, possibly due to a hydrogen concentration gradient; therefore, the presence of dislocations may assist hydrogen segregation and cause the high hydrogen flux.

回复 Gavriljuk 和 Teus 对论文“氢渗透下银装饰演化的原位观察：晶界错误取​​向对纯铁中氢通量的影响”的评论

摘要 作为对 Gavriljuk 和 Teus 评论的回应，我们讨论了充氢引起的裂纹形成和塑性变形对纯铁中沿晶界的高氢通量的影响。由于在我们研究中使用的纯铁试样的微观结构中没有观察到裂纹，因此可以排除裂纹形成的影响。相反，在晶界附近观察到位错定位，可能是由于氢浓度梯度；因此，位错的存在可能有助于氢偏析并导致高氢通量。
