Abstract
The effect of hydrogen on the critical shear stress (τcr), dislocation structure, and mechanisms of straining (slip vs. twinning) in single crystals of Fe-26Cr-32Ni-3Mo (wt %) austenite stainless steel has been studied. It is shown for the first time that hydrogenation leads to the appearance of the orientation dependence of τcr, which is absent in the initial hydrogen-free crystals. This dependence of τcr is related to a decrease in the stacking fault energy, which determines a change of the mechanism of straining from slip to twinning.
