Abstract

Abstract: Effect of pre-treatment before asynchronous rolling on the texture and formability of 6016 aluminum alloy sheet was investigated by tensile test, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that pre-aging treatment before asynchronous rolling can increase the strength of the aluminum alloy sheet without significantly reducing its plasticity, and its plane anisotropy IPA value is significantly reduced; plastic strain ratio $\bar{r}$ value and cupping value I_E are improved and reach 0.89 and 8.27 respectively. The main reason for the better comprehensive performance of the aluminum alloy sheet is the increase in the strength of the shear texture E{111}<110> and F{111} <112> and the decrease in the grain size.

Key words: pre-treatment, asynchronous rolling, aluminum alloy, texture, formability
