摘要

Features of structure and property formation are studied for cold-rolled product in two-phase ferriticmartensitic steels by modeling heat treatment in a continuous annealing unit (CAU) of six laboratory melts of different chemical composition intended for preparing steels of different strength classes according to EN10338:2013. Steel of some melts, apart from alloying with elements currently used extensively, are additionally alloyed with aluminum. Hot- and cold-rolling processing regimes simulate those used under production conditions. Results of modeling heat treatment in a CAU by different regimes show an increase in strength and a reduction in ductility properties with a reduction in overageing temperature. Rolled product of steel alloyed with aluminum has lower strength properties, ratio of yield to ultimate strengths, but better relative elongation values.
