Abstract Scope |
In nuclear power plants, dissimilar metal welded joints are widely existing, and those welds are indicated to be vulnerable points against the safe operation of the plants. In this study, we explored the laser additive manufacturing as a potential alternative to produce the components with dissimilar metals joints. We combined a suite of experimental techniques, including synchrotron x-ray based ultrafast imaging and high-speed diffraction, electron microscopy, and nano-indentation, to study the effect of laser parameters on the joining process, microstructures, and mechanical properties of dissimilar metal systems. We studied two systems relevant to nuclear applications, including the G91 steel + 316 stainless steel, and Alloy 690 Ni-based alloy + 316 stainless steel. Our preliminary study shows that the novel experimental approach used in this study can accelerate the development of additive manufacturing for nuclear applications. |
