dc.description.abstract | We develop high-strength of Al-Zn-Mg-Cu-based alloys (7xxx series) by optimizing the amount of Mg/Cu with a trace addition of Sc. The highest mechanical properties are achieved with sigma(UTS)=672 MPa (sigma(y) = 644 MPa) and epsilon = 8.6%. Based on quantitative symmetry measurements, the improved mechanical strength originates from nanoscopic structural distortion caused by the excessive solutes of Mg and Cu as the amount of Mg/Cu increases. In addition, Sc microalloying induces grain refinement, thus enhancing the mechanical properties. (C) 2021 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. | - |
