Effect Of Precipitation On The Texture Evolution During Rolling Of Continuous Cast2037Aluminum Alloy

2xxx aluminum alloy is a typical age-hardening alloy. Because of its high strength,excellent processability, heat resistance and other advantages, it has a very broadapplication prospects in many fields, especially in the field of aerospace.3xxx and5xxxaluminum alloys have been studied extensively by twin-belt continuous casting process.But2xxx aluminum alloy produced by the twin-belt continuous casting process has beenrarely reported. In this paper, the2037aluminum alloy has been studied for effect ofprecipitation on the texture evolution during rolling.The results show that: The hot band of the CC AA2037aluminum alloy possesses atypical deformed structure and a strong β fiber rolling texture. After solution treatmentat500℃for2h, the hot band was fully recrystallized. And then aged at150℃aftersolution treatment. As the aging times increased, the value of the electrical resistivitydecreased, and the amount of the precipitations increased. The precipitate produced byaging affect the texture evolution of2037aluminum alloy during cold rolling. First, thedistribution of orientation intensities along the β fiber can be affected by precipitates of2037aluminum alloy. The original orientation of2037aluminum alloy rotated to β fiberorientation during cold rolling. More original orientation rotated to S and C orientations ofβ fiber orientation as the aging times increased. This suggests that the precipitates arehelpful for the formation of the S and C orientations. In addition, the rate of textureevolution can be affected by precipitates of2037aluminum alloy. Establish an equation ofthe2037aluminum alloy texture volume to true strain, which can simulate textureevolution of the2037aluminum alloy in the process of rolling. The formation anddisappearance rate of the texture component can be analyzed quantitatively by the ki valuein these formulae. The disappearance of the cube+r-cube component decreased and therate of disappearance of the remainder component increased as the aging times increased.The rate of formation of of the fiber rarely changed during aging.
