Strength–Ductility Synergy in a Peak-Aged Low-Cu Al-Zn-Mg-Cu-Zr Thin-Walled Extruded Profile: Coupling of η′ Precipitation and Heterogeneous Grain Structure

To elucidate the strength–ductility synergy in a peak-aged low-Cu Al-Zn-Mg-Cu-Zr thin-walled extruded profile, the mechanical properties, precipitation behavior, and grain structure of the alloy were systematically investigated after solution treatment at 470 °C for 2 h followed by single-step aging at 120 °C for 8–48...
