Abstract��The processing conditions of the texture formation and deep drawability of a Ti��IF steel strip hot��rolled in ferritic region and subsequently annealed were investigated. The r��value increases with the decrease of reheating temperature, and finish rolling temperature and the increase of reductions in ferritic region. For lubricated ferritic rolling and annealing, the r��value is raised up to 1��75, and elongation rate is over 50% at the finish rolling temperature of 650 ��, which is suitable for DDQ grade products. However, the r��value is below 1��0 in the case of unlubricated rolling. The X��ray diffraction was used to analyze the textural characteristic of samples. For samples subjected to lubricated rolling and annealing, the strong {111}��ND recrystallization texture is distributed homogeneously along the thickness direction, and the intensity of {110} recrystallization texture is very low even in surface. However, for unlubricated samples, the {111} texture is distributed inhomogeneously and is weak along the thickness direction, and {110}��ND recrystallization texture is strong, which deteriorates the formability.
