ABSTRACT:
A superior high-temperature strength aluminum alloy material is produced by consolidating rapdily solidified particulates of an aluminum alloy into a desired configuration, the aluminum alloy consisting of, in weight percentages, 4 to 15% Fe, and 0.5 to 8% V and the balance being essentially aluminum. The aluminum alloy may further contain at least one element selected from the group consisting of 0.5 to 8% Mo, 0.5 to 8% Ni, 0.3 to 8% Zr and 0.5 to 8% Ti and these additional components develop a further increased strength in the resulting formed materials. Since the consolidated aluminum materials above specified have a superior strength at high temperatures as well as moderate temperature without an expensive Ce, they are highly useful as economical heat-resistant materials for various applications, particularly for the fields where high strength at high temperatures and lightness of weight are required.
