The alloy of the present invention is excellent in the hardness and strength at both room temperature and a high temperature, and also in thermal resistance and ductility. In addition, it is usable as a high specific strength material having a high strength and a low specific gravity due to a small amount of addition of rare earth element or elements.

    摘要: An aluminum-based alloy having the general formula Al.sub.x L.sub.y M.sub.z (wherein L is Mn or Cr; M is Ni, Co, and/or Cu; and x, y, and z, representing a composition ratio in atomic percentages, satisfy the relationships x+y+z=100, 75.ltoreq.x.ltoreq.95, 2.ltoreq.y.ltoreq.15, and 0.5.ltoreq.z.ltoreq.10) having a metallographic structure comprising a quasi-crystalline phase possesses high strength and high rigidity. In order to enhance the ductility and toughness of the aluminum-based alloy, the atomic percentage of M may be further limited to 0.5.ltoreq.z.ltoreq.4, and more preferably to 0.5.ltoreq.z.ltoreq.3. 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.
