摘要: Superplastic forming of aluminum work stock is improved by including therein about 0.05% to about 10% or 15% scandium together with up to 0.2 or 0.25% zirconium. In preferred practices, soluble elements such as magnesium are also included in the aluminum alloy. One or more of the elements from the group of scandium, yttrium, gadolinium, holminum, dysprosium, erbium, ytterbium, lutetium, and terbium, may be included in addition to or in lieu of scandium. Heat treatable aluminum alloys such as 7XXX alloys and 2XXX alloys can be made superplastic by including scandium and zirconium to provide very high strength in superplastically formed products.

摘要: There is disclosed an improved memory disk stock comprised of an alloy composition which includes: about 1-11 wt. % magnesium, preferably between about 2-7 wt. % Mg; up to about 0.3 wt. % zirconium preferably about 0.02-0.25 wt. % Zr; up to about 0.2 wt. % iron, up to about 0.2 wt. % silicon, and about 0.02-0.2 wt. % of a dispersoid-forming element selected from scandium, erbium, thulium, lutetium, ytterbium, hafnium and yttrium, the balance aluminum and incidental elements and impurities. With preferably about 0.05-0.15 wt. % of scandium added to such compositions, these disk stocks exhibit significant room temperature yield strength increases over the same compositions without any scandium added.
