The effect of Zn content on the age-hardening response and precipitation behavior for Al–8Si-0.6Mg-0.1Cu alloys by Lili Hu, Chenggang Wang, Feng Li, Jingqi Zhang, Maohui An, Jinguo Wang, Ruifang Yan

“…However, for the sample of 0Zn and 0.9Zn, the precipitates consist of β'' phase and trace Q′ phase, the Mg–Zn precipitation phase is not found in the microstructure. Finally, a precipitation schematic is proposed based on the precipitation behaviour of the three alloys, which reveal the evolution of the microstructure of the Al–8Si-0.6Mg-0.1Cu-XZn (X=0, 0.9, 3.6) alloy.…”
