Abstract Scope |
Prediction of microstructure evolution during material processing is essential to control the material properties. Simulation tools for microstructure evolution prediction based on physical concepts are computationally expensive and time-consuming. Therefore, they are not practical when there is an urgent need for microstructure during the process. Essentially, microstructure evolution prediction is a spatiotemporal sequence prediction problem, where the prediction of material microstructure is difficult due to different process history and chemistry. We propose a generative adversarial networks-long short-term memory (GAN-LSTM) model for the microstructure prediction by combining the generating ability of the GAN with the forecasting ability of the LSTM network. As a case study, we used a dataset from spinodal decomposition simulation of FeCrCo alloy created by the phase-field method for training and predicting the future microstructures by previous observations. The results show that the trained network is capable of efficient prediction of microstructure evolution. |
