Abstract

Abstract:

The effect of cold rolling deformation on the texture of aluminum alloy was studied by means of optical microscope and SEM. The results show that the recrystallization texture Cube{001}<100> will be replaced by deformation textures Copper{112}<111> and S{123}<634> via Goss{011}<100> with the increase of cold rolling deformation, and these deformation textures will be the main and stable orientations, but the volume fraction of Goss texture tends to increase first and then decrease. The texture of deformation band is mainly composed of Copper{112}<111> texture with high intensity and Cube{001}<100> texture with weak intensity. When the cold rolling deformation is less than 20%, the main grain orientations are {001} and {012}, and when the cold rolling deformation is more than 40%, the main orientations are {011}, {112}, and {123}.
