摘要	Ultrafine-grained Cu-Al alloys were prepared via friction stir processing (FSP) with additional rapid cooling. These FSP Cu-Al alloys exhibited equiaxed recrystallized grains with relatively low dislocation density and a high fraction (96%) of high-angle grain boundaries. Abundant annealing twin boundaries were successfully introduced into the ultrafine grains in FSP Cu-15Al (at.%) alloy, resulting in superior strength ductility synergy with a yield strength of similar to 700 MPa and a uniform elongation of similar to 13%.
