## Description

- description: 'Enhancement of thermally activated dislocation motion by solute hydrogen
    (H) has been envisaged in Fe–Cr–Ni austenitic steel through accelerated stress
    relaxation and a prolonged creep duration. Nevertheless, differences in the imposed
    stress/strain between the compared non- and H-charged samples at the starts of
    these mechanical transients, as well as involvements of other obstacles (e.g.,
    alloying elements and forest dislocations), mask the essential effects of H. We
    performed stress relaxation and strain rate jump tests at multiple stress/strain
    for Type310S austenitic steel with ∼7600 at ppm H at 296 K. The measured strain
    rate sensitivity (SRS) was evaluated via a methodology so-called Haasen plot.
    By screening the latent factors above, primary role of H was revisited: they work
    as short-range obstacles, hindering the dislocation movement. Multiple H atoms
    potentially participate in each thermal activation event, giving rise to a stress-equivalent
    activation volume and a proportionality between H concentration and yield strength.'
