This paper reports an investigation on the evolution of texture and plastic anisotropy during uniaxial tensile testing of extruded profiles produced from two variants of an AlZnMg alloy: one contains Zr and shows a non-recrystallized structure; the other is Zr-free and shows a recrystallized structure. Tensile tests were carried out at 0°, 45° and 90° from the extrusion direction and from which, experimental r-values were derived from quadratic polynomial functions fitting to the width and thickness strains in the tensile tested samples. The r-values and Taylor factors for the initial and tensile tested samples were simulated from the measured textures using the full constraints and relaxed constraints Taylor models. The results show remarkable differences in textures and anisotropy in the two profiles. Although the initial textures of the profiles are much sharper, the texture development in the tensile tests follows similar tendencies commonly observed in sheet metals. In general, the r-values predicted from the textures depict the same tendencies of variation with tensile strain as those for the experimental r-values, suggesting that the variation of plastic anisotropy is mainly caused by the texture evolution. The Taylor factors were used to simulate the in-plane anisotropy in yield strength and subsequent work hardening. For the latter, a better agreement with the experimental data was obtained when the texture changes due to tensile deformation was taken into consideration.

“…It is well known that the deformation texture components of Copper f112gh11 " 1 1i, Brass f110gh112i, R-cube f001gh110i and S f123gh6 " 3 3 " 4 4i contribute to 45 earing while the recrystallization texture cube f001gh100i, Goss f011gh100i results in earing in 0/90 direction. 9,10) However, there are some differences in physical and mechanical properties between aluminum and copper, which results in the total difference in texture evolution. Take pure-copper metal sheet for example, the deformed texture component will transit to some recrystallization textures which mainly consist of a cube-orientation and with it twins, 11,12) and which is not observed obviously form aluminum material undergoes the same thermal-mechanical process.…”

Experimental Investigation on Earing Behavior of Aluminum/Copper Bimetal Sheet

et al. 2006

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 Ár= " r r 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.
