In the context of the fatigue life design of components, particularly those destined for use in hydrogen refuelling stations and fuel cell vehicles, it is important to understand the hydrogen-induced, fatigue crack growth (FCG) acceleration in steels. As such, the mechanisms for acceleration and its influencing factors are reviewed and discussed in this paper, with a special focus on the peculiar frequency dependence of the hydrogen-induced FCG acceleration. Further, this frequency dependence is debated by introducing some potentially responsible elements, along with new experimental data obtained by the authors.This article is part of the themed issue 'The challenges of hydrogen and metals'.
在部件的疲劳寿命设计背景下，尤其是那些用于加氢站和燃料电池汽车的部件，了解钢中氢致疲劳裂纹扩展（FCG）加速现象非常重要。因此，本文对加速机制及其影响因素进行了综述和讨论，特别关注氢致FCG加速的特殊频率依赖性。此外，通过引入一些可能起作用的因素以及作者获得的新实验数据，对这种频率依赖性进行了探讨。本文是主题为“氢与金属的挑战”的特刊的一部分。
