ABSTRACT:
To provide a high-strength, high-ductility cast aluminum alloy, which enables a near-net shape product to be produced by improving the casting structure of an aluminum alloy, particularly by using specific constituents and controlling the cooling rate, and a process for producing the same. The high-strength, high-ductility cast aluminum alloy of the present invention is characterized in that it has a structure comprising fine grains of .alpha.-Al, having an average grain diameter of not more than 10 .mu.m, surrounded by a network of a compound of Al-lanthanide-base metal, the .alpha.-Al grains forming a domain, that the domain comprises an aggregate of .alpha.-Al grains which have been refined, cleaved, and ordered in a single direction and that it has a composition represented by the general formula Al.sub.a Ln.sub.b M.sub.c wherein a, b, and c are, in terms of by weight, respectively 75%.ltoreq.a.ltoreq.95%, 0.5%.ltoreq.b<15%, and 0.5%.ltoreq.c<15%.
