AbstractTensile strength of Cu-Al alloy is prominently enhanced by decreasing the stacking fault energy (SFE). In contrast, the uniform elongation (UE) depends strongly on the SFE and grain size. With decreasing the SFE, the UE of the Cu-Al alloy becomes increasingly sensitive to the grain size. In the coarse-grained regime, the UE is monotonically enhanced with decreasing the SFE, but in the fine-grained regime, the Cu-Al alloy with the medium SFE displays the highest UE. Strain-hardening behavior is investigated to clarify the ductility sensitivity to the SFE and grain size in the Cu-Al alloys.
