Thermal Aging of Dissimilar-Metal Weld Joints for Reactor Pressurized Vessels at Elevated Temperature

The purpose of this study is to investigate the thermal aging of dissimilar metal welds for reactor pressurized vessels in the primary system of nuclear power plants. The influences of long-term aging of dissimilar-metal welds on microstructural and mechanical characteristics have been studied qualitatively and quantitatively. The dissimilar-metal welds composed of SA 508 Cl.3 low alloy steel and AISI 316L stainless steel are prepared after...
