In the present work, an Al-0.66Mg-0.85Si-0.2Cu alloy with Zn addition was investigated by electron back scattering diffraction (EBSD), high resolution electron microscopy (HREM), tensile and Erichsen tests. The mechanical properties of the alloy after pre-aging met the standards of sheet forming. After paint baking, the yield strength of the alloy was improved apparently. GP(II) zones andη?phases were formed during aging process due to Zn addition. With the precipitation of GP zones,β″phases, GP(II) zones andη?phases, the alloys displayed excellent mechanical properties.
