摘要: A study has been conducted investigating the effect of reversed austenite on stress corrosion cracking property a chemically modified 17-4PH with specially designed two-step tempering in simulated geothermal environment. Two specimens very similar 0.2% proof and different contents were used to (SCC). Slow strain rate testing (SSRT) hydrogen precharged under cathodic polarization confirmed detrimental embrittlement. SSRT anodic involvement active path SCC environment, showed that was also detrimental. However, not able resolve most impacted property, initiation, or propagation.
