Effect of scandium on the structure and properties of alloy Al-5.5% Zn-2.0% Mg
Commercial weldable aluminum alloys additionally containing scandium have recently been developed in Russia: thermally nonhardening alloys based on the system Al-Mg (01570, 01523, 01515), and thermally hardening alloys based on the systems Al-Zn-Mg (01970, 01975) and Al-Mg-Li (01421, 01423). Compared with other weldable aluminum alloys these materials exhibit improved operating properties. This is achieved as a result of a small addition of scandium which displays a high modifying effect and it promotes retention of an unrecrystallized structure for alloys. Results are presented in this article for a study of the effect of scandium content on the structure and properties of pressed strips and cold-rolled sheets of alloy Al-5.5% Zn-2.0% Mg.
