NSUF 18-CINR-14788: Irradiation Testing of Materials Produced by Additive Friction Stir Manufacturing
The purpose of this work is to perform irradiation and post-irradiation examination of materials produced by the MELD process ( FKA additive friction stir, AFS) and analogous advanced manufacturing technologies, potentially including laser powder bed additive manufacturing, hot isostatic pressing (HIP) bonding and diffusion bonding. MELD is an innovative, disruptive, and potentially transformative solid-state thermomechanical process that was recently pioneered and demonstrated by Aeroprobe. It holds enormous potential for efficient near-net shape fabrication and joining of many alloys. This truly additive solid-state thermomechanical process can be used for manufacturing (of similar or dissimilar metals), repair, and coating. Significant work performed by Aeroprobe demonstrated that this technique permits the manufacturing of materials with equivalent or improved properties compared with wrought materials. Compared with other additive manufacturing technique, MELD is much faster, generates a refined equiaxed structure, and does not require the post-manufacturing treatments needed for processes based on melting and solidification, like selective laser melting (SLM) and direct metal deposition (DMD).To use this technique for fabrication of Light Water Reactors (LWR), Small Modular Reactors (SMR) and advanced reactor internal components, it is necessary to evaluate the effect of irradiation on the material properties, which is the main goal of this project. This project will also permit the comparison of the material generated with MELD with the same material generated by laser powder bed fusion additive manufacturing, technique investigated for Westinghouse.
