title = "On the failure of surface damage to assess the hydrogen-enhanced deformation ahead of crack tip in a cyclically loaded austenitic stainless steel",
abstract = "The influence of internal hydrogen on the plastic deformation ahead of a crack tip in a cyclically loaded austenitic stainless steel was determined through examination of the surface slip steps and dislocation structure. The slip steps failed to capture the totality of the sub-surface plasticity, causing the dimensions of the plastic zone generated in the presence of hydrogen to be underestimated. Regions in the hydrogen-charged steel that displayed no slip steps exhibited a similar dislocation structure to regions with slip steps in the uncharged steel. These observations are attributed to hydrogen-accelerating deformation processes and the rate of microstructure evolution.",
