Effect of hydrogen on nanomechanical properties in Fe-22Mn-0.6C TWIP steel revealed by in-situ electrochemical nanoindentation
Wang, Dong; Lu, Xu; Deng, Yun; Guo, Xiaofei; Barnoush, Afrooz (Journal article; Peer reviewed, 2018)In-situ electrochemical nanoindentation was applied to study the effect of hydrogen on the mechanical properties of Fe-22Mn-0.6C TWIP steel at nanoscale. Distinctive behaviors in three defined grain orientations: (001), ... -
Effect of hydrogen on the embrittlement susceptibility of Fe-22Mn-0.6C TWIP steel revealed by in-situ tensile tests
Wang, Dong; Lu, Xu; Wan, Di; Guo, Xiaofei; Johnsen, Roy (Peer reviewed; Journal article, 2020)The hydrogen embrittlement (HE) behavior on a Fe–22Mn-0.6C twinning-induced plasticity (TWIP) steel was investigated by tensile tests with in-situ scanning electron microscope observation combined with electron backscatter ... -
Reveal hydrogen behavior at grain boundaries in Fe-22Mn-0.6C TWIP steel via in-situ micropillar compression test
Lu, Xu; Wang, Dong; Wan, Di; Guo, Xiaofei; Johnsen, Roy (Peer reviewed; Journal article, 2022)In this study, the effect of hydrogen on dislocation and twinning behavior along various grain boundaries in a high-manganese twinning-induced plasticity steel was investigated using an in situ micropillar compression test. ...
