- •
Mg(Zn,Cu,Al)2 had the structure similar to MgZn2 containing Al and Cu elements.
- •
The composition of Mg(Zn,Al,Cu)2 was not affected by the homogenization treatment.
- •
Very few S phase that transformed from Mg(Zn,Cu,Al)2 phase was found when Zn% > 8.0 wt.%.
- •
Homogenization time increased with thickness and spacing of Mg(Zn,Cu,Al)2 phase.
