Fig.1 Engineering ultimate tensile strength (Eng. UTS) versus engineering uniform elongation (Eng.UE), showing the strength-ductility trade-off in alloys, adapted from Ref.[2], tailoring alloy composition in Cu alloys (a, b) and in steels (c) alleviates the trade-off, shifting the banana-shaped curve to a higher level (as indicated by the arrows)
