Abstract Scope |
Predicting the mechanical properties of stainless steel is challenging due to the complex and nonlinear composition-process interactions. Conventional experimental approaches require significant time and cost to investigate these interactions. While data-driven approaches using statistical analysis or machine learning have been introduced, they typically rely on large datasets and suffer from overfitting in limited datasets. To address these issues, we propose a metallurgy-guided graph convolutional network (MG-GCN) framework that learns the correlation between composition-process-properties even with small datasets by utilizing metallurgical information. With solid solution and precipitation strengthening as prior knowledge, a graph is constructed where alloy compositions are used as node features and heat treatment conditions are used as edge features. MG-GCN uses this graph as an input to learn metallurgical correlations and predict tensile properties from them. This approach achieves Rē values above 0.8 for predicting three tensile properties even when trained on just 40% of the data. |
