## Description

- description: Hydrogen embrittlement has long been an obstacle to the development
    of safe infrastructure. However, in contrast to hydrogen's embrittling effect,
    recent research has revealed that the addition of hydrogen improves both the strength
    and uniform elongation of AISI Type 310S austenitic stainless steel. A detailed
    understanding of how hydrogen affects the deformation mechanism of this steel
    could pave the way for the development of more advanced materials with superior
    properties. In the present study, in situ neutron diffraction experiments were
    conducted on Type 310S steel with and without hydrogen-charged to investigate
    the effect of hydrogen on the deformation mechanism. In addition to the effect
    of solid-solution strengthening by hydrogen, the q-value, a parameter representing
    the proportion of edge and screw dislocations in the accumulated dislocations,
    was quantitatively evaluated using CMWP analysis on neutron diffraction patterns.
    The comparison of q-values between the hydrogen-charged and non-charged samples
    reveals that hydrogen has minimal effect on dislocation character in Type 310S
    steel.
