Claim:
An aluminum alloy having high strength, ductility, corrosion resistance and fracture toughness, comprising: an amorphous phase aluminum alloy comprising about 4 to 25 weight percent of nickel and about 2 to about 25 weight percent of cerium; a coherent L1 2 phase comprising: about 4 to about 25 weight percent nickel and about 2 to about 25 weight percent of cerium, at least one first element selected from the group consisting of about 0.1 to about 4 weight percent scandium, about 0.1 to about 20 weight percent erbium, about 0.1 to about 15 weight percent thulium, about 0.1 to about 25 weight percent ytterbium, and about 0.1 to about 25 weight percent lutetium; at least one second element selected from the group consisting of about 2 to about 30 weight percent gadolinium, about 2 to about 30 weight percent yttrium, about 0.5 to about 5 weight percent zirconium, about 0.5 to about 10 weight percent titanium, about 0.5 to about 10 weight percent hafnium, about 0.5 to about 5 weight percent niobium, and about 0.5 to about 15 weight percent iron; the balance substantially aluminum wherein the volume fraction of the amorphous phase ranges from about 50 percent to about 95 percent and the volume fraction of the coherent L1 2 phase ranges from about 5 percent to about 50 percent.
