摘要：
The effect of dissolved hydrogen (DH) on the corrosion fatigue crack growth (CFCG) behavior of 316LN stainless steel (SS) was investigated in high temperature pressurized water. The results indicated that DH slightly increased the CFCG threshold stress intensity range ( Delta K th ) value by 9 % and significantly increased the corrosion fatigue crack growth rate (CFCGR) value by 35 %. On the one hand, DH promoted a large plastic zone formed ahead of the crack tip. On the other hand, DH addition transformed the crack growth mechanism from mainly the slip -dissolution without DH addition to the competition between the slip -dissolution and mechanical fatigue.
