【正文】 e after hot rolling. It was confirmed that by a suitable set of size of previous cold reduction and parameters of the following heat treatment it is possible to influence a plex of mechanical properties of individual strips. Trends of the particular obtained curves in all graphs reflect the wellknown relation between strength and plastic properties. Formability of the studied HSLA steel rises and vice versa strength properties fall with an increasing temperature of recrystallization annealing. Demands of the client on resulting mechanical properties of the HSLA steel strip can vary a lot. With regard to this fact it is of course not possible to establish a generalpurpose optimal annealing mode. The experimentally obtained particular trends of strength and plastic properties may be utilized for optimization of conditions of heat treatment of the investigated HLSA steel QStE 420 in a cold rolling mill, reflecting the specific requirements for a relation between strength and plastic properties of the given steel strips. The experiment should be supplemented by additional TEM analyses explaining the behaviour and role of precipitates during recrystallization annealing.Acknowledgements This work was done in the framework of solution of the project MSM6198910015, supported by the Ministry of Education, Youth and Sports of the Czech Republic.References [1] J.
