Notes:
In order to improve deep drawability of 6000 series aluminum alloys for automotive bodypanels, texture control for increasing r-value of the sheets was attempted by combination ofsymmetric and asymmetric rolling. Asymmetric warm rolling at relatively low reduction aftersymmetric rolling made it possible to form TD-rotated β-fiber texture including {111} components.Recrystallization textures of the T4-treated materials varied significantly depending on roll speedratio and reduction in asymmetric warm rolling. On appropriate rolling conditions, {111}〈110〉orientation with high r-value was formed as a main component of recrystallization texture. On theother hand, two-stage heat treatment consisting of low temperature annealing and subsequentT4-treatment led to a significant change in recrystallization texture. In the sample annealed for longtime at a low temperature, TD-rotated β-fiber rolling texture was retained even after solutiontreatment at a much higher temperature, because recovery or recrystallization took place to someextent during low temperature annealing
