Abstract
Disclosed is a single-phase amorphous alloy having an enhanced ductility. The single-phase amorphous alloy has a composition range of A100-a-bBaCb where a and b are respectively 0<a<15, 0≦b≦30 in atomic percent. Here, A includes at least one element selected from the group consisting of Be, Mg, Ca, Ti, Zr, Hf, Pt, Pd, Fe, Ni, and Cu. B includes at least one element selected from the group consisting of Y, La, Gd, Nb, Ta, Ag, Au, Co, and Zn. C includes at least one element selected from the group consisting of Al, In, Sn, B, C, Si, and P.
