Methods to increase solid solution zirconium in aluminum alloys
Abstract
A method of making an aluminum alloy containing zirconium includes heating a first composition comprising aluminum to a first temperature of greater than or equal to about 580° C. to less than or equal to about 800° C. The method further includes adding a second composition including a copper-zirconium compound to the first composition to form a third composition. The copper-zirconium compound of the second composition has a molar composition of greater than or equal to about 41% zirconium to less than or equal to about 67% zirconium and a balance of copper. The method also includes solidifying the third composition at a cooling rate of greater than or equal to about 0.1° C./second to less than or equal to about 100° C./second to a second temperature less than or equal to a solidus temperature and decomposing the copper-zirconium compound at a third temperature of less than or equal to about 715° C.
