Texture of samples, taken from recrystallized HS-IF steel, was analyzed via EBSD method. The beginning of texture-related modifications was not in accordance with mechanical properties’ modification. More prominent texture modifications were recorded at annealing temperature higher than 750oC. Severe softening was observed at such temperature because the recrystallized ratio reached 90%. After annealing at higher temperature, higher amount of grains with orientation {111} was observed, at the expense of orientation {100}. The first recrystallization nuclei were created in places with orientation {111}, where the highest energy during cold forming was stored; the nuclei had orientation {111}. Due to in situ nucleation the original orientations were conserved. It appears that oriented growth mechanism starts only after oriented nucleation mechanism is depleted.
