Comparative analysis of SCC susceptibility in Ni-base alloys N06600 (a) and N08810 (b). The bars represent a feature contribution to the predicted energy absorption rate α. Positive (red) contributions increase α, while negative (blue) contributions decrease α, starting from the base value \({\phi }_{0}\) = – 2.703. a In alloy N06600, Ni and Cr contribute the most to the α value of – 4.012, with other elements and \({\sigma }_{R}\) having minimal impact. b In N08810, the synergistic effect of Ni, Cr, and Cu results in a lower α value of – 5.11, enhancing its SCC resistance compared to N06600.
