| Abstract Scope |
Corrosion of structural materials in the presence of molten salts is a major challenge in molten salt reactors. Metal ion solutes generated from impurities, corrosion and fission products can significantly affect the corrosivity of molten salts. The fundamental mechanisms of microstructure and chemical evolution during molten salt corrosion in the presence of metal ion solutes remains unclear. In this work, we studied corrosion of simple Ni-20Cr model alloy with and without metal ion solute additives. This talk will discuss key corrosion events such as intergranular and intragranular attacks, selective dissolution, and changes in oxidation states, etc. characterized using advanced scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS), focused ion beam (FIB) tomography and atom probe tomography (APT) techniques. This work was supported as part of the Molten Salts in Extreme Environments (MSEE) Energy Frontier Research Center (EFRC), funded by the U.S. Department of Energy, Office of Science. |
