Rapidly solidified high-temperature aluminum iron silicon alloys
High-strength, lightweight alloy components, such as automotive components, capable of high temperature performance comprising aluminum, silicon, and iron and/or nickel are provided, along with methods of making such high-strength, lightweight alloy components. A high-energy stream, such as a laser or electron beam, may be selectively directed towards a precursor material to melt a portion of the precursor material in a localized region. The molten precursor material is cooled at a rate of greater than or equal to about 1.010.sup.5 K/second to form a solid high-strength, lightweight alloy component comprising a stable ternary cubic phase having high heat resistance and high strength. The stable ternary phase may be Al.sub.xFe.sub.ySi.sub.z, where x ranges from about 4 to about 5 or about 7.2 to about 7.6, y is about 1.5 to about 2.2, and z is about 1. The stable ternary phase may also be Al.sub.6Ni.sub.3Si.

Methods to increase solid solution zirconium in aluminum alloys
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.
