Effect of Preheat Treatment on the Texture Evolution During Cold Rolling of AA 3003 Aluminum Alloy

摘要

The effect of preheat treatment on the texture evolution during rolling of AA 3003 aluminum alloy was investigated by x-ray diffraction. The texture evolution during rolling was quantified in terms of a simple relation between the texture volume fractions and true rolling strain. It was found that the alloy annealed at 538 degrees C had a higher value of k(i) and a lower value of n(i) than the alloy annealed at 593 degrees C for all the texture components. The difference in texture evolution between the two preheat treatments was mainly attributed to the initial texture. The alloy annealed at 538 degrees C had a higher formation rate of b fiber component than the alloy annealed at 593 degrees C because of the relatively weak cube texture and the presence of the P texture.
