► Nanostructured Cu and Cu-Al alloys were prepared by high-pressure torsion. ► The strengths increase with decreasing stacking fault energy (SFE). ► The strength of NS alloys with low Al content is sensitive to the loading conditions. ► The ductility also increases except at the lowest SFE where the...
