Abstract
A high-strength and high-ductility aluminum-base alloy consisting of a composition of general formula: Al.sub.ba1 Mn.sub.a Si.sub.b or Al.sub.ba1 Mn.sub.a Si.sub.b TM.sub.c (wherein TM is one or more elements selected from the group consisting of Ti, V, Cr, Fe, Co, Ni, Cu, Y, Zr, La, Ce and Mm; and a, b and c are, in atomic percentages, 2.ltoreq.a.ltoreq.8, 0.5.ltoreq.b.ltoreq.6, 0<c.ltoreq.4, and a.gtoreq.b), wherein the alloy contains quasi-crystals. The an aluminum-base alloy have superior mechanical properties such as high hardness, high strength and high ductility.
