摘要
总结了近年来Al-Zn-Mg-Cu-Sc-Zr六元系相图的发展情况,分析了Al-Zn-Mg-Cu-Sc-Zr六元系中富铝角存在的中间相Al3Sc、Al3Zr、Al3(Sc1-xZrx)、W相(ScCu6.6~4Al5.4~8)、T相((Al,Zn,Cu)49 Mg32、Mg3 Zn3 Al2)、M相(或η相、MgZn2)及它们的相结构,概述了Sc、Zr添加对Al-Zn-Mg-Cu合金的有益作用,指出了Al-Zn-Mg-Cu-Sc-Zr六元相图的价值和研究方向。
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 system and its development trends are pointed out.
