Sažetak

This paper deals with mechanical properties of galvannealed automotive steel sheet. The composition of the zinc coating modifies as a result of the annealing after galvanizing, thereby its local mechanical properties change. Presented research is therefore aimed at determination the change in tensile properties of steel due to annealing, which is an important part of galvannealing technology. Annealing of galvanized steel samples was carried out at 500 °C with different holding times at annealing temperature. Changes in both tensile strength and normal anisotropy coefficient, a decrease of yield strength and an increase of ductility were found for examined steel.
