Abstract
A rapidly solidified aluminum base alloy consists essentially of the formula Al.sub.bal Fe.sub.a Si.sub.b X.sub.c, wherein X is at least one element selected from the group consisting of W,Ta,Nb, 'a' ranges from 3.0 to 7.1 at %, 'b' ranges from 1.0 to 3.0 at %, 'c' ranges from 0.25 to 1.25 at % and the balance is aluminum plus incidental impurities, with the provisos that the ratio [Fe+X]:Si ranges from about 2.33:1 to 3.33:1 and that the ratio Fe:X ranges from about 16:1 to 5:1. The alloy exhibits high strength, ductility and fracture toughness and is especially suited for use in high temperature structural applications such as gas turbine engines, missiles, airframes and landing wheels.
