Two Al-3%Mg alloys, one containing a fine dispersion of stable Al-Sc-Zr particles, have been deformed. to large strains in plane strain compression at a range of temperatures. The present paper discusses the development of texture during the deformation processing of these alloys. Microstructures and textures have been measured by high resolution electron backscatter diffraction (EBSD) in a FEGSEM. At low deformation temperatures, typical banded deformation microstructures and rolling textures are developed in both alloys, and the rolling textures persist at high strains, even when approximately equiaxed "ultra-fine" grain structures are formed by continuous recrystallization. However, as the deformation temperature is increased, a stronger cube texture develops in the alloy which does not contain the fine particle dispersion. The increase in cube texture correlates with an increase in grain size due to dynamic grain growth, and there is evidence that cube-oriented grains become significantly larger than others.
