## Description

- description: The influence of hydrogen on fatigue crack growth (FCG) was investigated
    in 90 MPa hydrogen gas using a 3Mn-0.2C martensitic steel with a tensile strength
    of 1500 MPa. Surprisingly, this steel exhibited significant crack closure in hydrogen
    gas under specific loading conditions, resulting in considerably lower FCG rates
    compared to those in air. The roughness- and plasticity-induced crack closure
    markedly retarded the FCG in hydrogen in a relatively low stress intensity factor
    regime. However, intrinsic FCG resistance, excluding the effect of crack closure,
    was indeed degraded by hydrogen. Further analysis revealed that the reduction
    in cohesive strength of block boundaries depended on the plastic zone size and
    the inclination angle between the longitudinal axis of the blocks and the macroscopic
    FCG direction. Consequently, hydrogen-enhanced plasticity-mediated decohesion
    led to cycle-dependent acceleration of FCG, even in such high-strength steel under
    high-pressure hydrogen environments.
