Abstract:
1. An alloy represented by a formula consisting essentially of: wherein a, b, c, and d are atomic fractions, in which 0.472≦a≦0.568; 0.09≦b≦0.11; 0.27≦c≦0.33; 0.072≦d≦0.088, and the sum of a, b, c, and d equals to 1; e and f are atomic numbers of elements Y and M respectively, in which 0.01≦e≦5, and 0.01≦f≦5; and M is selected from the group consisting of Nb, Ta, Sc, and combinations thereof, wherein the alloy has an amorphous phase of more than about 95% by volume, wherein the alloy has an amorphous phase of more than about 95% by volume, wherein M is selected from the group consisting of: the combination of Sc and Nb, the combination of Sc and Ta, and the combination of Sc, Nb, and Ta, and wherein the atomic ratio of Sc to Nb ranges from about 1:from about 0.1 to about 5, the atomic ratio of Sc to Ta ranges from about 1:from about 0.1 to about 5, and the atomic ratio of Sc:Nb:Ta ranges from about 1:from about 0.1 to about 5:from about 0.1 to about 10.
