- •
A new spray deposited Al-Zn-Mg-Cu-Zr-Sc alloy is studied.
- •
Microstructures evolution with various Sc contents is analyzed.
- •
The primary Al3(Sc, Zr) particles can act as nucleation sites for the η-MgZn2 phase.
- •
An excellent combinations of strength of 831 MPa and elongation of 10.2% is obtained.
