Abstract Scope |
Modeling the microstructure evolution and linking them to materials properties is critical in establishing processing-structure-property linkage in materials. In this project, the evolution of microstructure of Fe-C alloys is modeled using phase field simulations to understand the behavior of these alloys under various cooling temperatures and initial carbon concentrations. However, these simulations require significant computational resources. Alternatively, in this work, a convolutional neural network (CNN) and recurrent neural network (RNN) were coupled with phase field simulations to predict the solidification of Fe-C alloys. In addition to the data-driven approach, the solid-liquid interfacial energy was incorporated during the training process, giving the model additional information regarding its performance, forcing it to learn more accurately using a smaller dataset. This work also gives insight as to how the dataset size, model complexity, and loss function can influence the performance of machine learning models in materials science applications. |
