Abstract

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).
