Abstract

Low-cycle fatigue (LCF) behaviors of 316LN in borated and lithiated high temperature water with different dissolved oxygen (DO) levels were investigated. The LCF lives of the material at different DO levels were different from the LCF lives predicted by the previous study. When DO levels were 50 ppb, 100 ppb and 2 ppm, hydrogen absorbed inside the material was negligible. Results suggest that the slip oxidation/dissolution mechanism works for 316LN and the main reason of LCF life reduction at < 5 ppb DO level was hydrogen induced cracking (HIC).
