Title:
HEALABLE SUPERPLASTIC AMORPHOUS ALLOY
Document Type and Number:
WIPO Patent Application WO/2023/191278
Kind Code:
A1
Abstract:
The present invention relates to a healable superplastic amorphous alloy and, specifically, to a healable superplastic amorphous alloy that can exhibit superplastic behavior and unique healable behavior by limiting the composition of a Zr-Cu-Ni-Al alloy and controlling additive elements to maximize the complexity of an amorphous structure so as to form an icosahedral quench core quasi-crystal cluster in an amorphous matrix.
