## Description

- description: Solute hydrogen (H) is recently identified to improve the strength
    and ductility of some Fe-Cr-Ni austenitic steels due to a combination of solid-solution
    hardening and accelerated deformation twinning. In the present study, the impact
    of deformation temperature (173∼373 K) on this ductilization effect was studied
    primarily under a slow strain rate in Fe-24Cr-19Ni steel pre-charged with 7570
    at ppm H. Ambient temperature was found to be an optimized condition where H-induced
    ductilization was the most pronounced. With the lowering temperature below 200
    K, ductilization was mitigated entirely in spite of still substantial H-induced
    twinning enhancement. The result was ascribed to an overly prompted twinning activity
    and its premature density saturation, encompassing a consummation of work-hardenability
    at an earlier deformation stage.
