Abstract：

The microstructure and texture evolution of 6014-T4P aluminum alloy in the industrial trial production process were analyzed by experimental analysis means such as metallographic microscope, X-ray diffractometer, scanning electron microscope and electron backscattering diffraction. The results show that the volume fraction of S texture in the three coils of hot-rolled trial material is more than that of Brass texture and Copper texture, and it also contains recrystallization texture with most volume fraction of R texture. After solution treatment, there are completely recrystallized grains in the trial-produced plates, and the grain distribution is relatively uneven, especially for the trial materials of B and C coils. The average grain sizes of the trial materials of A,B,C coils are 31.25, 37.16 and 31.25 μm, respectively. The rough rolling passes (11 and 13 passes) have little effect on the grain size. The Cube texture of the T4P state trial material of coil A is obviously smaller than that of trial materials of B and C coils, and the volume fraction ratio of S texture and Cube texture is 1.65∶1. The hemming performance of T4P state trial material of coil A is better, but the roping is more serious. At the same time, the proportions of 2°-5° small angle grain boundaries in the T4P state trial materials of A,B and C coils are 35.0%, 17.9% and 24.0%, respectively.
