Characterization of Multi-layer Weld Metal and Creep–Rupture Behavior of Modified 10Cr–1Mo Welded JointChang-Zhen Zhang,Chen-Dong Shao,Hai-Chao Cui,Hua-Li Xu,Feng-Gui LuShanghai Key Laboratory... 10Cr–1Mo steel multi-layer welded joint is determined by the fine-grain zones of the weld metal adjacent to the fusion line during the long-term creep test at 620 °C. The microstructures of multi-layer......
the surface strain distribution in the weld metal of a full thickness welded joint specimen and subsequently to investigate the local variation in the properties of the all-weld metal part of the joint... thickness large welded joint specimens, HAZ and all-weld metal miniature specimens. From the results obtained, it is concluded that the creep properties of multi-layer welded joints strongly depend......
, Harbin 150001,China) Abstract:Friction stir welding achieves the weld in solid phase by locally introducing frictional heating and plastic flow arising from rotation of the welding tool, which results... including dynamically recrystallized,equaxied grains in the weld nugget. Residual hardness in the nugget was found slightly lower than the parent but not too obvious. Key words:friction stir welding......
