Fig. 7: SHAP waterfall plots of SCC in SS alloys.
From: XGBoost model for the quantitative assessment of stress corrosion cracking
Comparative analysis of SCC susceptibility in SS alloys S30400 (a) and S31000 (b). Here, SHAP waterfall plots illustrate the contribution of each feature to the predicted energy absorption rate α. Each bar indicates the directional effect of a feature, with positive (red) contributions increasing α, and negative (blue) contributions decreasing α, starting from the base value \({\phi }_{0}\) = – 2.703. a The combined effect of alloying elements in S30400 results in a positiveα value of 1.897, indicating a relatively high susceptibility to SCC. b The high Ni and Cr content in S31000 contribute to a low value of -3.421, indicating enhanced SCC resistance.
