Abstract

A high strength dispersion strengthened aluminum alloy comprising an aluminum solid solution matrix strengthened by a dispersion of particles based on the compound Al.sub.3 X, where Al.sub.3 X has an L1.sub.2 structure, is described. Various alloying elements are employed to modify the lattice parameter of the matrix and/or the particles so that the matrix and particles have similar lattice parameters. The alloy is produced by rapid solidification from the melt.
