Improved creep forming efficiency and retained performance via a novel two-stage creep aging process of Al–Zn–Mg–Cu alloys

A novel two-stage creep aging forming (CAF) process with an elevated temperature followed by peak-aging temperature was developed to notably improve the creep forming efficiency and to achieve a favorable combination of strength and corrosion resistance in an Al–Zn–Mg–Cu alloy. Compared with traditi...
