Abstract：Microstructure and texture evolution of low-carbon Cr-Mo deep drawing dual-phase steel were investigated by using microstructure observation, TEM and XRD. The results show that, the finish-rolling process conducted in austenite no-recrystallization zone promoted the formation of {112}〈111〉 component. The intensity of {001}〈110〉,{112}〈110〉 and {223}〈110〉 orientations were steadily enhanced during cold rolling.The formation of sharper 〈111〉//ND, {554}〈225〉 and {332}〈113〉 textures during annealing was favorable to improve the deep draw-ability of dual-phase steel. When intercritical annealed at 820℃ and 860℃, the intensity of γ-fibre was slightly different. The difference of intensity between {111}〈110〉 and {111}〈112〉 texture tended to increase at high-temperature annealing, causing by the solution-carbon of bainite and the variant selection from austenite to bainite. The high-temperature coiling process induced precipitation of Mo-based carbide in hot-rolled strips, and re-dissolution during the holding stage in annealing process, which not only facilitated the formation of recrystallization textures, but also improved the second phase transformation.
