The effect of hydrogenation on strain hardening and deformation mechanisms in 〈113〉 single crystals of Hadfield steel

The effect of hydrogenation on the strain-hardening behavior and the deformation mechanisms of 〈113〉-oriented single crystals of Hadfield steel was investigated under tension at room temperature. The stages of plastic flow and deformation mechanisms for hydrogen-charged specimens are similar to one in hydrogen-free state: slip → slip + single twinning → slip + multiple twinning. Hydrogen alloying favors to mechanical twinning, micro- and macrolocalization of plastic flow.
