An aluminum alloy with high strength at high temperature includes an aluminum matrix with over 80 molar % aluminum and L1precipitate phases having a maximum dimension no greater than 20 nm in the aluminum matrix. The L1precipitate phases have a formula of AlM, wherein M in the L1precipitate phases comprises at least one of erbium and zirconium. This alloy and other compositions as well as the processing conditions for producing the compositions can be formulated via a computer-implemented method involving evaluation of material properties of simulated products formed from a plurality of precursor compositions.
