Abstract Scope |
Advances in nuclear fusion reactors core architecture have led to consider metallic additive manufacturing (AM) as the prime manufacturing process, especially for components with highly complex internal structures. Depending on the size and shape, LPBF or DED are envisioned for the production of parts. Plasma-Facing Components (PFCs) are the parts of the reactor’s vacuum vessel meant to withstand extreme conditions of neutron and particles irradiation, temperature and corrosion. Among proposed PFC materials, tungsten is the leading candidate to shield the Eurofer97 steel structural components of the reactor core. However, joining those two materials with laser AM poses a serious, multifaceted challenge. Bi-layered specimens of tungsten on Eurofer97 were printed using LPBF and DED; formation of intermetallic phases at the interface and the resulting stress/strain field was studied using synchrotron X-Ray Diffraction and Neutron Bragg Edge Imaging. |
