Abstract
Aluminium sheets of commercial purity were cold-rolled from hot-rolled stocks without intermediate annealing. It was found that the anisotropy of annealed sheets was influenced by hot-rolling condition. During cupping test three types of earing property were observed; i.e., 45° ear, 90° ear and a mixture of 45° ear and 90° ear. The prefered orientation of annealed sheets was investigated by means of X-ray. The recrystallization texture consisted of a (123)-[1\bar21] type texture component and a cube texture component. It was found that the cube texture component increased with decreasing hot rolling-temperature. From the correlation of the results of cupping test and the recrystallization texture, it is assumed that an increase in cube texture component was the cause of 90° earing.
