The development of texture inhomogeneity during hot rolling of Ti/Nb-bearing interstitial free steel was investigated for various processing parameters. {l_brace}225{r_brace}<554>, {l_brace}001{r_brace}<110> and {l_brace}225{r_brace}<110> are suggested as attractors of texture components during hot rolling, which are related by a 30{degree} <110> orientation relationship. The texture inhomogeneity of the resulting ferrite after hot rolling is related to the through thickness change of the main texture components of the parent austenite. It is proposed that the transformation from the austenite texture to the ferrite texture occurs by a 30{degree} <110>{parallel}TD rotation. The 30{degree} <110>{parallel}TD rotation is equivalent to an orientation relationship that is {l_brace}225{r_brace}{sub {gamma}}{parallel}{l_brace}001{r_brace}{sub {alpha}} and <554>{sub {gamma}}{parallel}<110>{sub {alpha}}, where {gamma} and {alpha} stand for austenite and ferrite, respectively.
