Abstract: The effects of continuous annealing process on the microstructure, texture and mechanical properties of high strength plastic cold rolled dual phase steel DP980 were systematically studied by setting the experimental parameters of continuous annealing process. The results show that, with the increase of annealing temperature, the annealed texture components increase obviously, and the shear texture components decrease gradually. The other texture components have no obvious characteristics and are randomly produced. The annealing texture is obviously enhanced, and the yield strength and tensile strength of the cold-rolled DP980 steel are gradually increased, and the strength and plastic product of the cold-rolled DP980 steel reaches 15 GPa·%.
