Abstract Scope |
The prediction of Transformation Temperatures (TTs) in new multicomponent Shape Memory Alloys (SMAs) is an extremely challenging task due to the complex, nonlinear, unequal, and competing impacts of alloying additions on resultant TTs. In this work, we compiled a database for medium and high entropy SMAs, which was extended by the calculation of HEAs compositional features. A deep learning framework was developed to predict the martensite start temperature in multicomponent SMAs. The model integrates Convolutional Neural Networks, Long-Short-Term Memory networks, and Transformer models to capture spatial, temporal, and long-range dependencies in the data. Feature engineering, using Lasso and Ridge regression, was employed to optimize the dataset and enhance model performance. The model's robustness was validated through extensive error analysis, highlighting its capability to generalize well on unseen data, offering a promising tool for the accelerated design of new and refinement of existing medium and high entropy SMA compositions. |
