The chemical composition of the Nb, Ti microalloyed steel was established. The rolling and cooling conditions in the thermomechanical treatment of sheets with a ferritic-martensitic (DP-type) structure and a ferritic-bainitic with retained austenite (TRIP-type) structure were determined. It was found that sheets produced according to this method have a fine-grained structure and better mechanical properties than after the classical underhardening or isothermal quenching from the temperature slightly higher than Ac1 of the investigated steel. Applied process conditions can be useful on integrated rolling line of multiphase structure sheets for the automotive industry.
