Textures of sheet in AA3003 aluminum alloy under biaxial stretching

In this paper, the textures are determined under plane strain tension, nonequi-biaxial stretching and equi-biaxial stretching. The changes of the major texture components in the sheet are analyzed and discussed. It is found that under plane strain tension, the strength of the {110}〈112〉 component increases by more than four times followed by the {110}〈111〉, whereas the fraction of {112}〈111〉 component falls gradually. In the sample deformed with a strain ratio intermediate between these of plane strain tension and equibiaxial stretching, the textural change is relatively small. Under equi-biaxial stretching, there is a big increase in the {110} rolling plane components with the peak at {110}〈111〉 orientation. The strength of the other components falls rapidly (e.g. {110}〈112〉) or remains low (e.g. {112}〈111〉).
