| Abstract: | Investigates the effects of hydrogen on the nucleation and propagation ofaquatic corrosion-fatigue cracks of 0Cr13Ni4Mo casting steel. The hydrogen-indu-ced failure of the steel is observed in both hydrogen diffusion and hydrogendissolution processes, and the hydrogen-induced failure is dependent on themicrostructure and harmful impurity content in the steel. |

| Keywords: | corrosion-fatigue hydrogen-induced failure apparent yield stress reversal austenite |
