Abstract
The effect of small tensile deformation (3, 6, and 10%) on the texture of preliminary annealed sheets of two-phase DP600 steel (0.10 C, 0.15 Si, 1.4 Mn, 0.007 P, 0.008 S, 0,009 N, 0.02–0,06 Al, 1 Cr–Mo–Ni (wt %)) is studied. Against the background of the annealing texture in the sheets, the {001} <110>, {111} <110>, {111} <112>, {111} <312> components of the slip texture and {115} <110>, {115} <552>, {221} <110>, {221} <114> orientations are developed, which can be associated with the twinning processes. The anisotropy pattern of the Young’s modulus (E) in the sheet plane remains the same after tensile deformation of the annealed sheets. After tension, the values of E decrease in all directions as a result of the onset and development of microdamages. The anisotropy of damage (D) in the plane of the steel sheets after tension is characterized by a maximum in the transverse direction (TD) and a minimum in the rolling direction (RD).
