| Abstract Scope |
Metal additive manufacturing processes are currently used to fabricate complex metal part shapes while maintaining mechanical and irradiation properties comparable to those fabricated via traditional means of cast and wrought processes. Increased deposition rates, repairing capability via cladding and the ability to produce near-net-shaped parts have significantly increased the adoption of directed energy deposition (DED) for fabricating and repairing parts. Zirconium (Zr) alloys are widely used for ATF cladding in LWRs; however, increased corrosion may occur due to contact with specific metallic components, such as Pt, Hf, Inconel also known as ‘shadow corrosion’. These observations had inclined us to investigate FeCrAl as the primary material for current research. In this study, we investigated the differences in resulting microstructure and property relationship of FeCrAl alloy fabricated via LDED and wrought routes. Additionally, the effect of varied laser power and scanning velocity on altering microstructure, porosity and microhardness were captured. |
