Abstract
An aluminum-based alloy having the general formula Al.sub.100 -(a+b)Q.sub.a M.sub.b (wherein Q is V, Mo, Fe, W, Nb, and/or Pd; M is Mn, Fe, Co, Ni, and/or Cu; and a and b, representing a composition ratio in atomic percentages, satisfy the relationships 1.ltoreq.a.ltoreq.8, 0<b<5, and 3.ltoreq.a+b.ltoreq.8) having a metallographic structure comprising a quasi-crystalline phase, wherein the difference in the atomic radii between Q and M exceeds 0.01 .ANG., and said alloy does not contain rare earths, possesses high strength and high rigidity. The aluminum-based alloy is useful as a structural material for aircraft, vehicles and ships, and for engine parts; as material for sashes, roofing materials, and exterior materials for use in construction; or as materials for use in marine equipment, nuclear reactors, and the like.
