Abstract

The effects of dissolved hydrogen (DH) on the low-cycle fatigue (LCF) behaviors and the hydrogen uptake inside the samples of 316LN stainless steel were investigated in simulated pressurized water reactor (PWR) primary water with various DH levels at a slow strain rate. DH showed no obvious effects on the fatigue life and no obvious influence of DH on the degree of the dynamic strain aging (DSA) was observed. The hydrogen uptake inside the samples slightly increased with increasing DH level. No obvious difference among the composition of oxide films formed in water with different DH levels was observed.
