| Abstract Scope |
Zirconium alloys are widely used in nuclear applications as accident tolerant fuel claddings in light-water reactors. However, due to contact with specific metallic components such as Pt and Hf, a type of corrosion known as “shadow corrosion” can occur. For this reason, we focused on FeCrAl as the primary material for our current research. Additionally, metal additive manufacturing processes are currently used to fabricate complex shaped metal parts while maintaining mechanical and irradiation properties comparable to those fabricated via traditional casting and wrought processes. Laser direct energy deposition (LDED) technique was adopted into fabricating and repairing parts due to its ability to produce near-net-shaped parts, increased deposition rates and repairing capabilities. In this study, we investigated the differences in the resulting microstructure-property relationships of FeCrAl alloy manufactured via LDED and wrought routes. Moreover, the effects of varied scanning velocity and laser power on altering microstructure, microhardness and porosity were measured. |
