摘　　要：Hydrogen-nduced delayed fracture occurs in hydrogen-charged austenitic stability stainless steel The fracture morphology changes from dimple to quasicleavage. The plastic zone and deformation in front of the notch increase with charging time during cathodic charging for austenitic stainless steel. This phenomenon
