| Abstract Scope |
316H stainless steel is a strong candidate material for advanced nuclear reactors due to its high mechanical strength, good corrosion resistance, and established use in high-temperature applications. Additive manufacturing (AM) enables the fabrication of materials with complex geometries to be designed for structural applications. The Department of Energy has chosen to focus on AM 316H, utilizing the laser powder bed fusion (LPBF) method, as a test case for rapid qualification of AM components. Due to its unique grain structure, the corrosion kinetics of AM 316H are largely unknown. Potentiodynamic polarization, square wave voltammetry, and cyclic polarization techniques are used to predict corrosion rates and analyze post-test salt composition at two temperature conditions (500 and 700<sup>°</sup>C). Scanning electron microscopy/energy dispersive X-Ray spectroscopy/electron backscatter diffraction (SEM/EDS/EBSD) and transmission electron microscopy (TEM) techniques are used to characterize the microstructure evolution and reveal corrosion mechanisms. |
