## Description

- description: 'Dissolution of atomic hydrogen (H) into Fe-Cr-Ni austenitic steels
    causes a significant increase in flow stress (i.e., solid solution-hardening,
    SSH) during their plastic deformation. In this study, the characteristics and
    kinetics of H-induced SSH in AISI Type 310S steel with 7600 at. ppm H were studied
    through the measurements of strain rate sensitivity, m, by stress relaxation and
    strain rate jump experiments at 296 K. Two factors were found to contribute to
    the SSH: (i) the role of H as thermally activatable obstacles that increase the
    effective stress; (ii) the resistance acting on moving dislocations due to their
    dragging of the H atmosphere (solute drag). These factors operated cooperatively
    or competitively in determining the m value and its dependencies on stress, strain,
    and strain rate. The peak SSH can be achieved where the sum of dislocation glide
    resistances from (i) and (ii) is maximized. The anticipated strain rate range
    for establishing such a situation coincided accurately with the author’s previous
    experiments.'
