Recrystallization in commercial grade interstitial-free steel, discussing criticality of martensite and massive ferrite nucleation along with mechanical property

Interstitial-free steel is very soft and ductile, with a fully ferritic microstructure at room temperature. In order to address this issue in the present work, the cold-rolling increases tensile strength vividly by strain hardening. The heat-treatment thereafter optimizes strength-ductility, with an...
