摘要： A process for preparing an aluminum alloy which can be produced on a commercial scale and has higher strength and toughness than the conventional aluminum alloys. The alloy comprises an alpha -aluminum phase comprising grains having an average diameter of 60 to 1000 nm and a phase of two or more intermetallic compounds comprising grains having an average diameter of 20 to 2000 nm, and the grains of the intermetallic compound are dispersed so that the connection between the intermetallic compound grains is intermittent.
