摘要	The trade-off relation between strength and plasticity is the bottleneck that limits the development of high-strength and high-plasticity Al-Cu alloys. Inspired from the influence of precipitate shape on the work-hardening behavior of Al-Cu alloys, an Al-Cu-Zr-Sc alloy containing a mixed microstructure of spherical-shaped Al3(Zr, Sc) phases and disk-shaped theta ' phases is successfully designed and fabricated. Surprisingly, it is found that the strength and plasticity of the Al-Cu-Zr-Sc alloy are synchronously improved compared to the Al-Cu alloy with only disk-shaped theta ' phases. The introduction of spherical-shaped Al3(Zr, Sc) phases can increase the yield strength without sacrificing the work-hardening ability of the Al-Cu-Zr-Sc alloy, which is mainly attributed to the extremely small strain-hardening exponent of the Al alloy with spherical-shaped precipitates. Besides, the predicted strength-elongation relation of the Al-Cu alloy is established based on the exponential strain-hardening model. An Al-Cu-Zr-Sc alloy containing a mixed microstructure of spherical-shaped Al3(Zr, Sc) phases and disk-shaped theta ' phases is fabricated, which shows a simultaneous improvement of strength and plasticity as compared with the Al-Cu alloy with only disk-shaped theta ' phases. Furthermore, based on the exponential strain-hardening model, the quantitative strength-uniform elongation relations of the Al-Cu alloy and the Al-Cu-Zr-Sc alloy are established.image (c) 2023 WILEY-VCH GmbH
