aging hardening Atom-probe analysis cast duplex stainless steel G-phase spinodal decomposition thermal-aging
In this study, thermal-aging evaluation has been performed using service aged elbow pipe in PWR plant, aged at 320℃ for 196,500h. As a result, micro Vickers hardness of ferrite in service material (SCS14A), HV(0.025) was 616~630. Since micro Vickers hardness of un-aged ferrite phase is about HV(0.025)=300 in commercial SCS14A, the increasing of ferrite hardness during aging was 300. Cr-rich and Fe-rich regions were observed in the ferrite phase using Atom-probe analysis. In addition, Ni, Si and Mo clus...

constant load test dissolved hydrogen IASCC microstructure PWR radiation-induced segregation stainless steel
(Times New Roman 10pt) should be about 150 words. Irradiation assisted stress corrosion cracking (IASCC) is one of the aging issues of LWR. INSS has been conducted the research on IASCC using flux thimble tube irradiated up to 73dpa in commercial PWR since 1990s. The increase of strength and hardness by microstructure change and microchemistry change such as grain boundary segregation were investigated. The increase of hardness and grain boundary segregation seem to be an important factor for IASCC in...
