Abstract
A high-strength aluminum-based alloy consisting essentially of a composition represented by the general formula: Al.sub.bal Mn.sub.a M.sub.b or Al.sub.bal Mn.sub.a M.sub.b TM.sub.c wherein M represents one or more members selected from the group consisting of Ni, Co, Fe and Cu, TM represents one or more members selected from the group consisting of Ti, V, Cr, Y, Zr, La, Ce and Mm and a, b and c each represent an atomic percent (at %) in the range of 2.ltoreq.a.ltoreq.5, 2.ltoreq.b.ltoreq.6 and 0<c.ltoreq.2 and containing monoclinic crystals of an intermetallic compound of an Al.sub.9 Co.sub.2 -type structure in the structure thereof. The Al-based alloy has excellent mechanical properties including a high hardness, high strength and high elongation.
