    Mechanism of Hydrogen-charged SUS310S Stainless Steel

## Description

- description: Recent studies have shown that the addition of hydrogen to SUS310S
    stainless steel (Fe–24Cr–19Ni, mass%) simultaneously enhances both strength and
    ductility, indicating a phenomenon contrary to the conventional understanding
    of hydrogen embrittlement. In this study, we investigated the underlying mechanism
    through in situ neutron diffraction experiments during tensile deformation using
    TAKUMI at the MLF of J-PARC. The results revealed that solid-solution strengthening
    by hydrogen plays the most significant role in improving the mechanical properties.
    Solute hydrogen atoms distort the lattice to suppress dislocation motion, thereby
    increasing the strength. The raised stress in the hydrogen charged sample enables
    the onset of deformation twinning at a smaller strain compared to the non-hydrogen
    charged sample. Consequently, the twinning-induced plasticity effect contributes
    more significantly to work hardening and the improvement of uniform elongation
    due to the solid-solution strengthening by hydrogen. These findings suggest a
    new pathway for the effective utilization of hydrogen in austenitic steels.
