    Abstract

    This study investigated effects of addition of O2 and CO to H2 gas environments on a hydrogen-accelerated fatigue crack growth in a pipe steel. Both O2 and CO inhibited the hydrogen-accelerated fatigue crack growth. The inhibitory effect of O2 was well-interpreted by the mechanism proposed by Somerday et al. (2013). On the other hand, different mechanisms, which are the reaction rate of CO with the iron surface and time for hydrogen diffusion in the material, dominated the inhibitory effect of CO.
