| Abstract Scope |
The relationships between composition, thermodynamic properties, solidification, and resulting microstructure is of great interest to increase High Entropy Alloys (HEAs) adoption into practical applications. However, predicting these characteristics presents significant challenges due to the complex, multi-component nature of HEAs resulting in a large design space with vast thermodynamic properties. To address this challenge, a multi-physics simulation framework and data-driven surrogate modeling approach are implemented, to provide a method to rapidly assess how changes in HEA composition will lead to changes in solidification profiles and ultimately microstructure. The physics-based framework sequentially couples CALPHAD for material properties, CFD for thermal conditions during solidification, and Cellular Automata for microstructure. A data-driven surrogate model, which can reconstruct microstructure statistics from the thermal conditions, is trained via a reduced-dimensional form of the microstructure output of the physics-based framework and results of the physics-based framework, surrogate model, and experimental EBSD are presented. |
