Abstract The advanced electron backscatter diffraction (EBSD) technique is used to study the orientation distribution function (ODF), the content of texture components and the intensity of the γ fiber of the interstitial-free steels annealed samples (after cold rolling). It is found that the existence of P may block the dislocation movement and the grain boundary migration leading to the grains to have the same orientation and the sharpe {111} plane texture. The adding of Ti results in the intensity of {554}<225> texture component in the cold-rolled samples, which is inherited to be the recrystallized texture. The misorientation between {554}<225> and {111}<112> texture components is only 6o. Therefore, the high quantity of {111}<112> is found in the high strength Ti-IF steels. Mechanism of effects of P and Ti on
the {111} plane texture is also discussed.
