Abstract
A process for producing an aluminum alloy with high strength and toughness includes the steps of: preparing an alloy blank having a primary structure which is one selected from a single-phase structure comprised of a solid-solution phase, a single-phase structure comprised of an amorphous phase, and a mixed-phase structure comprised of a solid-solution phase and an amorphous phase, and subjecting the alloy blank to a thermal treatment to provide an aluminum alloy which has a secondary structure containing 20% or more by volume fraction Vf of chrysanthemum-like patterned phases each having a diameter of at most 5 .mu.m and comprising a solid-solution phase and an intermetallic compound phase arranged radiately.
