Enhanced strength–ductility synergy in nanostructured Cu and Cu–Al alloys processed by high-pressure torsion and subsequent annealing
Enhanced strength–ductility synergy in nanostructured Cu and Cu–Al alloys processed by high-pressure torsion and subsequent annealing
Nanostructured Cu and Cu–Al alloys processed by high-pressure torsion were isochronally annealed to investigate the effects of the stacking fault energy (SFE) on strength and ductility. All metals exhibit a similar general trend that the strength decreases and the ductility improves with increasing annealing temperatures, and a notable enhancement of ductility was achieved only when the volume fraction of recrystallized grains exceeded ~80%. The strength–ductility synergy improves significantly with decreasing SFE

Abstract
Nanostructured Cu and Cu–Al alloys processed by high-pressure torsion were isochronally annealed to investigate the effects of the stacking fault energy (SFE) on strength and ductility. All metals exhibit a similar general trend that the strength decreases and the ductility improves with increasing annealing temperatures, and a notable enhancement of ductility was achieved only when the volume fraction of recrystallized grains exceeded ~80%. The strength–ductility synergy improves significantly with decreasing SFE
