Influence of Annealing Temperature on Properties and Texture of High Strength IF Steel
Using the cold rolled High Strength IF Steel sheet of 1.0 mm thickness as the test material,the r value and recrystallization texture were investigated by the tensile test and X Radial Diffraction Device.The results show that the test steel were annealed by heating to 760°C,800°C,840°C and holding sixty seconds,and with the increase of the annealing temperature ,the recrystallization finished and the texture to obtain the full evolution,and the r value of the steel grown.After the annealing,the recrystallization texture shows strong γ-fiber texture,homogeneous γ-fiber and weak α-fiber texture,and the texture strength change rule with the annealing temperature change was gained.
