Texture evolution of 01570 aluminum alloy sheet

Abstract

The texture configuration and evolution mechanism of 01570 aluminum alloy, under different stabilizing annealing systems, were studied by means of observations of optical microscopy and analysis of X-Ray. The results show that the major textures of 01570 alloy sheet, at cold-rolling condition, are of Brass texture{011}<211>, Copper texture {112}<111> and S texture{123}<634>; especially, the strength of Brass texture is strongest. Below the recrystallization temperature to make stabilizing annealing, the texture components change little compared with the cold-rolling sheet. When stabilizing annealing temperature reaches the recrystallization temperature, the deformation texture will disappear with the temperature rising gradually, and the recrystallization texture configuration will gradually increase; when the temperature reaches 590°C, the major textures are of the recrystallization texture of rotating cube texture and cube texture in the alloy.
