Abstract The microstructure and tensile properties of steels 15 and 15Mn2Nb after quenching from intercritical (γ + α) temperatures were studied. It was shown that steel 15 has an “island-type” dual-phase structure (ferrite plus martensite) after intercritical quenching, while the steel 15Mn2Nb has the “lamellar” structure with alternatively arranged ferrite and martensite needles. Such a lamellar dual-phase structure obviously has improved strength and ductility and is suggested as one of the effective methods in developing high strength dual-phase steels.
