Abstract: A new method is proposed to predict the earing behavior of polycrystallme Aluminum sheet. The method is based on the Tucker's theory of earing proposed for single crystals by consideration of the partition of the orientation space. The number, position and relative heights of earing tendency for some important ideal orientations in single crystal aluminum was calculated. The calculated result is the same with the result from Tucker's theory. The new method was used to predict the earing behavior of the material with no texture, cold rolled sample, recrystallization sample arid the finish product from South-Western Aluminum plant. It is shown that the predictions are in good agreement with experimental results. The texture can be regulated and adjusted according to the earing behavior of polycrystalline aluminum alloy sheet predicted by the method. This is also very useful in the fast prediction system of texture-property on production line.
