Texture evolution and earing in aluminium can sheet

The texture evolution during hot and cold rolling of A1Mg1Mn1 can body sheet is described and the related anisotropy effects during deep drawing are analysed quantitatively. The typical textures of rolled aluminium show the transition between beta-fibre orientations and cube recrystallization texture, depending on rolling temperature and strain. These correlate with transitions between 45 degrees and 0 degrees/90 degrees ear heights in deep drawn cups which are described by a new method of Fourier series expansion. Processing parameters to achieve low anisotropy are discussed.
