    • The present invention provides high strength, heat resistant aluminum-based alloys having a composition represented by the general formula, Al a M b X c
      wherein:
      M is at least one metal element selected from the group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, Zr, Ti, Mo, W, Ca, Li, Mg and Si;
      X is at least one metal element selected from the group consisting of Y, La, Ce, Sm, Nd, Hf, Nb, Ta and Mm (misch metal); and
      a, b and c are atomic percentages falling within the following ranges:
      50 ≦ a ≦ 95, 0.5 ≦ b ≦ 35 and 0.5 ≦ c ≦ 25,
      the aluminum-based alloy being in an amorphous state, microcrystalline state or a composite state thereof. The aluminum-based alloys possess an advantageous combination of properties of high strength, heat resistance, superior ductility and a good processability which make then suitable for various applications.
    • 本发明提供具有由通式AlaMbXc表示的组成的高强度,耐热的铝基合金,其中:M是选自V,Cr,Mn,Fe,Co,Ni中的至少一种金属元素, Cu,Zr,Ti,Mo,W,Ca,Li,Mg和Si; X是选自Y,La,Ce,Sm,Nd,Hf,Nb,Ta和Mm(混合稀土金属)中的至少一种金属元素; 和a,b和c是原子百分比,它们在以下范围内:铝基合金(50),其中, 处于非晶状态,微晶状态或其复合状态。 铝基合金具有高强度,耐热性,优异的延展性和良好加工性能的有利组合,从而适用于各种应用。
