Phase-field methods include the geometry of the microstructure explicitly and can therefore be higher fidelity than analytical approaches to modeling microstructure evolution. For the complex alloy systems of practical interest, however, phase-field models are limited by computational performance and the need to specify many kinetic and thermodynamic model parameters. Performant open-source phase field codes have been developed, but the challenge of appropriately parametrizing phase-field models remains complex and time-consuming, even for experienced users. To address this challenge, we are developing AMMBER, the AI-enabled Microstructure Model BuildER, which will provide an automated process for extracting phase-field parameters from many different sources of kinetic and thermodynamic data. In the current stage of this project, we are generating thermodynamic parameters for phase-field simulations of microstructure evolution.
