Investigation On Texture Evolution Rule Influence The Formability Of The5B02Aluminum Alloy Pipe

The thin-walled pipe of5B02aluminum alloy were researched in this paper, the5B02aluminum alloy were annealed and simulated the plastic deformation capability by CAEsoftware; consulting the process of5B02pipe to decide the process of5B02rolling, thetexture changing would provide reference for the plastic deformation process of5B02aluminum alloy.The results showed that the5B02aluminum alloy tensile strength were decreased in therecommended limits and the ductility property was enhanced after annealing between330℃to400℃for1or2hours. The plastic deformation capability of the sample which annealed at380℃/2h is better than other samples.It shown that the original pipe had strong Goss texture component, after annealing, theGoss texture component was disappeared, and the Cube texture component was obvious. Withthe temperature of annealing was growing up, the C texture component would be stronger.Annealed at380℃/2h, the cube texture was obviously weaken, and the C texture wasunformed. The dispersive texture type maybe the reason that the plastic deformationcapability of the sample which annealed at380℃/2h is better than other samples.The grain was easily to appear the orientation in the plastic deformation of5B02aluminum alloy cold rolling. It would be improve the finally plastic deformation capability touse the suitable hot rolling for reducing the texture levels. The result of finite element methodsimulate shown that the annealed380℃/2h is better than the original pipe at the deformationprocess of bending. Bending radius is more than3times the pipe diameter, the pipe annealedat380℃/2h can bend any angle less than180°without wrinkling、rupturing and Crosssection distortion.
