Figure 5. Two-stage design of the L1₂-strengthened Co-base superalloys. (A) Research framework; (B) Two-stage design: Stage 1 uses the RFC model to determine the existence of γ′ precipitates; Stage 2 employs the RFR model to predict the γ′ solvus temperature; (C) Prediction results of the RFC on the training dataset by 10-fold cross validation; (D) Prediction results of the regression models on the training dataset^[50]. RFC: Random forest classifier; RFR: random forest regressor.
