Abstract

Results are presented from a study of dual phase ferritic-martensitic steels (DFMS) of two compositions: 0.08% C, 1.18% Si, 1.81% Mn, and 0.39% Cr; 0.07% C, 1.16% Si, 1.79% Mn, 0.40% Cr, and 0.14% V. In order to obtain different structural parameters in the two DFMS, heat treatments were given to 3.2-mm-thick specimens of steel sheet with different initial structures: the ferrite-pearlite-bainite mixture obtained directly from hot rolling; a ferrite matrix with spheroidized carbides, obtained by heating the hot-rolled sheet and holding it at 1050°C for 1 h, cooling the sheet with the furnace to 690°C, holding the sheet at this temperature for 15 h, and then further cooling the sheet together with the furnace. The results confirmed the positive effect of “new” ferrite on the ductility of DFMS. This effect is connected not with the intrinsic properties of new ferrite but with the factors that help increase the initial volume of this component in the steel (the amount of new ferrite in the investigated steels ranges up to 20–25%).
