Abstract

Al 7075 alloy was equal and di erential speed rolled according to various deformation routes. In these routes the sheets were rotated around di erent axes between subsequent passes of rolling. The mechanical properties and the microstructure of the specimens processed by various routes were compared. It was found that while the strength values were irrespective of the rolling routes, the ductility depends strongly on the deformation method. The di erences in the mechanical behavior were explained by the edge/screw character in the dislocation structure.
