Abstract Scope |
Machine learning is emerging as a new computational tool in the field of materials science. Recently, a machine learning based grain growth model named PRIMME (Physics-Regularized Interpretable Machine Learning Microstructure Evolution) was developed to study isotropic grain growth. In this work, a systematic investigation is carried out to study the impact of the training dataset on the robustness and reproducibility of the growth kinetics of the PRIMME model. Various initial conditions were considered to generate training datasets using the Monte Carlo Potts model and the Phase-field method. Results show that the PRIMME model trained with polycrystal training datasets simulates large scale two-dimensional grain growth reasonably well, but microstructural features are dependent on the training dataset. Also, simulating circular grain growth evolution is strongly dependent on the training dataset. A modified PRIMME model is under development to overcome these challenges. |
