摘要: 本文从两个实际人造水晶釜开裂形态观察及产物分析入手,研究丁CrNiMo低合金高强度钢在NaOH,水溶液中SCC及CF行为,提出人造水晶釜开裂的类型、机理及提高抗断裂能力的途径。试验结果还表明对CrNiMo低合金钢-NaOH水溶液体系,CF过程中的SCC行为可以降低CF裂纹扩展速率。

Abstract：In this paper the fractography and corrosion product analysis of fractured pressure vessels for growth of cultured quartz crystals were analysed, and the behaviour of stress corrosion cracking(SCC), corrosion fatigue(CF) of CrNiMo low alloy steels in NaOH solution were investigated systematically. The results reveal that the fracture of pressure vessels for growth of cultured quartz crystals is caused by CF. For the CrNiMo low alloy steel-NaOH solution system, a platen was observed in the da/dn versus ΔK curves, but the mechanism does not to SCC, the da/dN in the second stage of CF is reduced by SCC in CF process.
