| 内容記述 | Since the Japanese reduced activation ferritic/martensitic steel named F82H is considered as the primary candidate structural material for application in water-cooled ceramic breeder test blanket module, qualification on weldability of F82H based on France regulation and construction code should be identified to aim for works at ITER environment. In this study, based on the proposed welding procedure specification (WPS), two test pieces (TP) were welded by the tungsten inert gas (TIG) arc welding method and turned to post-weld heat treatment. Welded TPs were conducted by non-destructive testing (NDT) and destructive testing (DT) to investigate welded performance including defect phenomena and mechanical properties. Out of acceptance criteria of welded TPs were not observed by NDT and DT investigations. It was indicated that TIG welded F82H including the welding process performed sufficient margin to satisfy the criteria of France regulation and construction code. The qualification on weldability of F82H could be validated according to the limited WPS and dimension of TPs. Furthermore, an extended evaluation on fatigue lifetime based on the modified universal slope method was performed. Compared with the base metal of F82H, the same magnitude of fatigue lifetime was observed at 550 ?C. |
