Optimization of processing parameters to improve ductile-to-brittle transition of low-carbon structural steel

Literature-derived dataset comprising nine compositional variants of Nb-microalloyed ferrite–pearlite HSLA steels (0.08–0.14 wt% C) was used to model Charpy impact behavior. A data-driven framework integrating evolutionary machine learning (EvoNN and EvoDN2) with multi-objective...
