dc.description.abstractThe effect of a Cu addition on a hydrogen embrittlement (HE) was studied in Fe-17Mn-0.8C TWIP steels with 0-2 mass% of Cu. As-rolled and hydrogen-charged samples were investigated by examining their microstructures, tensile properties, fracture behaviors, and hydrogen-related characteristics. Diffusible hydrogen was mainly trapped at the grain boundaries in the present steels, the amount of which was similar regardless of the Cu composition. However, the Cu addition clearly enhanced the HE resistance of the alloys. It was revealed that the Cu addition did not change the HE mechanism but affected the HE rates. The hydrogen-charged steels exhibited heterogeneous intergranular fractures due to the limited diffusion of hydrogen. The mechanism of the retarded HE in Fe-Mn-C-Cu TWIP steels was the mitigation of the applied stress on grain boundaries and the uniform distribution of hydrogen. These mechanisms were wholly different from those reported in Fe-Mn-C-Al TWIP steels in spite of the similar improvements in the HE resistance. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
