Development of Cube Texture during Industrial Processing of High Purity Aluminum Foil Obtained with 99 Volume Fraction of Cube Component

摘要

The formation behavior of Cube texture during industrial process in high purity aluminum foil obtained 99% in volume fraction of Cube component was investigated. The Cube-oriented grains after the intermediate annealing were preferentially located in the C- and S-oriented fine microstructure, and were also observed less in the Brass-oriented coarse bands of the cold rolled foils. Furthermore, the fine microstructure bands and the strong - fiber texture of hot rolled material were the origin of the high density of Cube grains after the intermediate annealing . It is extremely important to control and to stabilize fine grain size and strong rolling textures of hot rolled material in order to obtain the volume fraction greater than 99% of Cube component in the final foil.
