The effect of Zn content on the age-hardening response and precipitation behavior for Al–8Si-0.6Mg-0.1Cu alloys
Published 2024-11-01“…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.…”
