High strength and ductile ultrafine-grained Cu-Ag alloy through bimodal grain size, dislocation density and solute distribution

Engineering stress-strain curves for RT and LNT rolled as well as the annealed Cu-3 at.% Ag alloys. Stress-strain data taken from the literature for DPD Cu [23], DPD and annealed Cu [23], HPT-processed Cu [32], ECAP-processed Cu-1.8 at.% Ag alloy [46] are also included for comparison.
