HYDROGEN-INDUCED FRACTURE OF A SUPER-HIGH STRENGTH STEEL UNDER CYCLIC LOAD OF LADDER WAVEFORM
梯形波周期加载下超高强度钢的氢致断裂

Hydrogen-induced fracture of electrolytic charged, sharp notched specimens ofsuper-high strength steel 30CrMnSiNi2A has been studied by means of cyclic ladder waveformloading tests and SEM examination. The results show that the time to fracture decreases withthe decrease of dwell period of the load. It was considered that hydrogen transported by disloca-tions significantly effects the hydrogen-induced delayed fracture of the steel.
