“…They concluded that HEE of the sensitized materials was not due to the carbides, but to the strain-induced martensite along the grain boundaries. This result and its interpretation is consistent with works of Brass et al [53] who investigated the influence of shot-peening on HEE of AISI 304 steel.…”

“…Measurements of hydrogen diffusivity in steels subjected to an elastic strain have shown little change in hydrogen diffusivity [11,19,20], consistent with the analysis above. Plastic strains, on the other hand, generate additional hydrogen traps, thus deformation affects hydrogen trapping and hydrogen transport [4,5,16].…”

The thermodynamics and kinetics of hydrogen dissolved in structural metals is often not addressed when assessing phenomena associated with hydrogen-assisted fracture. Understanding the behavior of hydrogen atoms in a metal lattice, however, is important for interpreting materials properties measured in hydrogen environments, and for designing structurally efficient components with extended lifecycles. The assessment of equilibrium hydrogen contents and hydrogen transport in steels is motivated by questions raised in the safety, codes and standards community about mixtures of gases containing hydrogen as well as the effects of stress and hydrogen trapping on the transport of hydrogen in metals. More broadly, these questions are important for enabling a comprehensive understanding of hydrogen-assisted fracture. We start by providing a framework for understanding the thermodynamics of pure gaseous hydrogen and then we extend this to treat mixtures of gases containing hydrogen. An understanding of the thermodynamics of gas mixtures is necessary for analyzing concepts for transitioning to a hydrogen-based economy that incorporate the addition of gaseous hydrogen to existing energy carrier systems such as natural gas distribution. We show that, at equilibrium, a mixture of gases containing hydrogen will increase the fugacity of the hydrogen gas, but that this increase is small for practical systems and will generally be insufficient to substantially impact hydrogen-assisted fracture. Further, the effects of stress and hydrogen trapping on the transport of atomic hydrogen in metals are considered. Tensile stress increases the amount of hydrogen dissolved in a metal and slightly increases hydrogen diffusivity. In some materials, hydrogen trapping has very little impact on hydrogen content and transport, while other materials show orders of magnitude increases of hydrogen content and reductions of hydrogen diffusivity.

“…12) Brass et al demonstrated that the hydrogen was trapped in the cold worked layer introduced by the SP using tritium autoradiography. 25) However, in this research, the increase of hydrogen trap site was not observed in the surface layer of SP treated specimen as shown in Fig. 7(b).…”
