The current status of study of Al-Zn-Mg-Cu-Sc-Zr hexbasic system in the aluminum-rich region in recent years is reviewed. The intermediate phase Al3 Sc, Al3 Zr, Al3 (Sc1-x Zrx), W phase(ScCu6.6~4 Al5.4~8 ), T phase ((Al,Zn,Cu)49 Mg32, Mg3Zn3Al2), and M phase(or η, MgZn2) in the aluminum-rich region of Al-Zn-Mg-Cu-Sc-Zr hexbasic system and their phase structures are analyzed, and the good effect of Sc and Zr addition on Al-Zn-Mg-Cu alloy is summarized, Finally, the research advantages of this sy...
