Grain size effects on strain localization and fracture behavior in ferrite–martensite dual-phase steels characterized by digital image correlation analysis

Dual-phase (DP) steels, consisting of soft ferrite and hard martensite phases, are widely utilized for their favorable balance of strength and ductility. Grain refinement in DP steels has been recognized as an effective strategy to enhance strength without sacrificing ductility, particularly in the...
