| Abstract Scope |
Molten salt reactors have recently gained renewed due to their enhanced safety. One of the technical challenges, however, is the need for structural materials that withstand the corrosive conditions of the molten salts. Before appropriate alloys can be developed, an understanding of how corrosion occurs, how the microstructure evolves subsequently, and how the mechanism may change under various temperature and salt chemistry must be developed. Under the support of Molten Salt in Extreme Environments Energy Frontier Research Center, we develop models and simulation tools to develop such understanding. We combine the phase-field modeling approach with the Smoothed Boundary Method to simulate dissolution of metals and subsequent microstructure evolution. Various phenomena are examined, including intergranular corrosion and coarsening of complex microstructures resulting from corrosion. The evolution of both experimental and simulated microstructures is quantitatively analyzed to provide scientific understanding, which can then be applied to mitigate degradation of these materials. |
