Abstract: The present disclosure relates to a healable superplastic amorphous alloy, and specifically, to a healable superplastic amorphous alloy capable of exhibiting superplastic behavior and unique healable behavior by maximizing the complexity of the amorphous structure for an Icosahedral quenched-in nuclei quasi-crystal cluster to be formed in the amorphous matrix through the composition limitation and additive element control of Zr—Cu—Ni—Al alloy.
