| Abstract Scope |
With recent advancements in metal additive manufacturing and hybrid additive manufacturing, there is a huge opportunity to engineer surfaces of nuclear energy components that can enhance the mechanical behavior critical alloys of interests in nuclear energy. In this talk, two major efforts being pursued will be discussed. In first case, fretting wear resistance of ODS-FeCrAl alloys deposited via laser directed energy deposition (L-DED) will be analyzed. FeCrAl alloys are promising materials that can improve the performance of accident-tolerant fuel claddings in nuclear energy applications due to their enhanced corrosion and oxidation resistance at elevated temperatures. The addition of Y2O3 nanoparticles modified the microstructure of FeCrAl alloys to further enhance the high temperature properties. On the second study, the effect of interlayer ultrasonic impact peening assisted L-DED was employed to develop nitrogen-strengthened austenitic stainless steel, and residual stress evolution along the build height was captured using neutron diffraction. |
