摘要 对不同冷变形量的核级316和316L不锈钢在高温水中的应力腐蚀开裂(SCC)行为进行了研究。通过试验,对溶解氧、氯离子和温度对裂纹扩展速率的影响进行了深入探讨和分析。试验结果显示,溶解氧和氯离子能明显加快材料的应力腐蚀开裂速率。当水化学条件一致时,325℃时的裂纹扩展速率较288℃时的裂纹扩展速率高。 The stress corrosion cracking（SCC）behaviors of different deformations of cold-deformed nuclear grade 316 SS and 316 LSS in high temperature water were studied.The effects of dissolved oxygen,Cl-and temperature on the crack growth rate were analyzed detailedly.Test results show that dissolved oxygen and Cl-can significantly increase the crack growth rate of the material.Moreover,the crack growth rates are faster at 325 ℃than that at 288 ℃ when water chemical conditions are the same.
