Abstract Scope |
In this study, we investigate the influence of training datasets generated from Monte Carlo Potts (MCP) and Phase-field (PF) simulations on the PRIMME (Physics-Regularized Interpretable Machine Learning Microstructure Evolution) model for isotropic grain growth prediction. Despite nearly identical initial conditions, the PRIMME model trained with MCP simulation data captures most normal grain growth characteristics but fails to reproduce the von Neumann-Mullins’ relationship and circular grain evolution. In contrast, the PRIMME model trained with PF simulation data successfully replicates all typical normal grain growth characteristics. Notably, both PRIMME models, whether trained with MCP or PF data, exhibit accelerated kinetics compared to the underlying training datasets, highlighting the significant impact of the simulation method on the model's learning behavior. This insight is invaluable for optimizing the PRIMME model's performance when training with experimental data. |
