Healable superplastic amorphous alloy

A healable superplastic amorphous alloy comprising Zr, Cu, Ni, Al and an additive element (X), said healable superplastic amorphous alloy being represented by Formula 1:

• ZraCub-cXcNidAlf [Formula 1]
• where X is a combination of two or more selected from the group consisting of V, Mo, Nb, Ta, Ag, and Hf, b-c is 2 or more and 29 or less, c is 1 or more and 10 or less, d is 2 or more and 29 or less, f is 6 or more and 18 or less, and a is 100−(b+d+f),
• wherein:
• the Ni and the Zr form a principal cluster;
• the additive element and the principal cluster form an icosahedral quenched-in nuclei (IQN) quasi-crystal cluster;
• the radius of the additive element is 75% or mor and 105% or less with respect to the atomic radius of the Zr;
• and
• wherein Equation 1 below is satisfied for the X in said Formula 1:
• ⅓(at. % of Nb)+⅓(at. % of Ta)+⅓(at. % of Mo)+ 1/7(at. % of V)+ 1/7(at. % of Hf)+⅙(at. % of Ag)≥1.0 [Equation 1].
