Due to the a drawing process in liquid nitrogen a drastic refinement of the microstructure of pure copper can be achieved by the activation of severe deformation twinning. In order to facilitate and enhance the refinement process an additional reduction of stacking fault energy by alloying can be applied. We are presenting the influences of severe deformation twinning on the microstructure and texture of copper and single-phase copper-aluminium alloys on the one hand and the mechanical and electrical properties on the other hand.
