Abstract

The effect of post-annealing treatment on the texture evolution of an Al/Cu bimetal sheet as well as on the earing behavior was investigated. The earing behavior was tracked by means of measuring plastic anisotropy and deep drawing. The analysis texture evolution for asrolled and annealed samples was performed by X-ray diffraction. The study results show that Δr/r̄ value increases and becomes positive when annealing temperature rises up to 300°C, in the meanwhile, a transition was observed from 45 to 0/90° earings. The mismatch in texture evolution between Al-side and Cu-side specimens was investigated. The typical recrystallization texture of Cu-side specimens mainly consists of a cube-orientation with its twins (CT) and cube texture develops at anneal temperature higher than 200°C. However, cube texture becomes the main component in Al-side specimen annealed at the temperature higher than 300°C. The mismatch in texture evolution between aluminum and copper has profound effect on the earing behavior of Al/Cu bimetal sheet. The analysis results of texture and plastic anisotropy were inductively reasoned to construct a prediction model of a Al/Cu bimetal material on earing. The earing behavior of Al/Cu bimetal material is depicted as a compromised result of the growth and decline in some certain texture components, which is agreement with the experimental findings obtained in this study.
