Abstract (en)

[origin: EP0710730A2] An aluminum-based alloy having the general formula Al100-(a+b)QaMb (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 </= a </= 10, 0 < b < 5, and 3 </= a+b </= 12) having a metallographic structure comprising a quasi-crystalline phase 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.
