Abstract Scope |
RAFM steel has been considered the candidate material for an in-vessel component of the fusion wall reactor. The goal of this research project is to fabricate and study the technical feasibility of wire arc additive manufacturing. A metal-cored wire is a tubular electrode comprised of an outer metal sheath with alloying powdered materials inside the core. The advantage of using the metal-cored wire is that a higher deposition rate, and higher side-wall fusion, can be achieved, and more important, special alloys such as RAFM steels can be manufactured at a relatively lower cost. Moreover, any undesirable elements can be excluded. A preliminary investigation of WAAM RAFM was carried out at the Georgia Southern AM lab. A design of experiments with different waveforms using the metal-cored wire was conducted to study the printability. The microstructure and mechanical properties were tested, analyzed, and compared with the available data from the literature. |
