比较了两种奥氏体合金在超临界水(SCW)中的应力腐蚀敏感性，并用扫描电子显微镜(STEM)揭示了SCC生长速率的定量差异。结果表明，在SCW环境下的SCC试验过程中，试件发生了原位敏化和蠕变。在应力腐蚀裂纹尖端前的晶界处，Fe-25Cr钢具有较高的贫化程度，由于其铬含量低于Ni-29.3Cr钢，其原位敏化程度较高，从而增加了蠕变敏感性。
This work compared the stress corrosion cracking (SCC) susceptibility of two austenitic alloys in supercritical water (SCW), and revealed the quantitative difference of SCC growth rates through scanning transmission electron microscopy (STEM). Results showed that in-situ sensitization and creep occurred on the specimens during the SCC tests in SCW environment. Higher degree of Cr-depletion at the grain boundary ahead of the SCC crack tip was identified in the Fe-25Cr steel specimen, which has suffered severer in-situ sensitization because of the lower Cr content than the Ni-29.3Cr alloy specimen, and this in turn increased the creep susceptibility.
