摘要

Features of microstructure formation for hot-rolled product of low-carbon steels microalloyed with titanium and molybdenum are studied. The possibility is demonstrated of achieving a high level of mechanical properties due to forming a volumetric system of nanosize complex (Ti, Mo)C carbide precipitates during cooling after hot rolling, including during cooling of a wound coil with gamma -> alpha transformation, and also as a result of forming a finely dispersed ferrite structure with increased dislocation density. Conformity of the temperature for the end of rolling and strip winding on a coil with a cooling regime in this temperature range, and also an increase in free titanium content in this steel, are desirable.
