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

316LN奥氏体不锈钢在不同溶氧水平含硼和锂化高温水中的低周疲劳行为

摘要 研究了 316LN 在不同溶解氧 (DO) 水平的硼化和锂化高温水中的低周疲劳 (LCF) 行为。材料在不同溶解氧水平下的 LCF 寿命与之前研究预测的 LCF 寿命不同。当溶解氧水平为 50 ppb、100 ppb 和 2 ppm 时,材料内部吸收的氢可以忽略不计。结果表明滑移氧化/溶解机制对 316LN 起作用,是 LCF 寿命降低的主要原因
