... affected intergranular fracture is often explained by the hydrogen enhanced decohesion (HEDE) mechanism. However, trace of plastic deformation is usually observed in the fracture surface, implying that hydrogen intergranular fracture is not a simple decohesion behavior. On the other hand, the governing...
