Crystal plasticity computation and atomic force microscopy analysis of the internal hydrogen-induced slip localization on polycrystalline stainless steel

A local approach combining atomic force microscopy measurements and finite-element calculations at the grain scale is proposed to study the effects of hydrogen on the slip morphology of polycrystalline austenitic stainless steel. The definition of a localization index highlighted the particularly visible effect of hydrogen on plastic slip localization in relation to the crystallographic orientation and the intragranular plastic strain level.
