Abstract: The effect of adding trace rare earth (Yttrium) on cold rolling texture and recrystallization texture of high purity aluminum is investigated and analyzed in detail by means of crystal orientation distribution functions (ODF). The experimental results show that the adding of trace yttrium has not changed the type of cold rolling texture. However, the cube recrystallization texture can be strengthened with the increasing of the content of element Y. The cube texture is the strongest when w(Y) is 0.001 5%. The rare element Y may combine with the other impurities to form metallic compounds, such as FeYAl₈, Fe₆YAl₆, Fe₄YAl₈, Si₁YAl₂, Si₂YAl₂ and Cu₄YAl₈. When the precipitation of these particles in the matrix is nearly completed and the Fe concentration in the matrix become low, the cube recrystallization texture develops well.
