Abstract

A Zr-based amorphous alloy and a method of preparing the same are provided. The Zr-based amorphous alloy is represented by the general formula of (ZraM1-a)100-xOx, in which a is an atomic fraction of Zr, and x is an atomic percent of 0, in which: 0.3≦a≦0.9, and 0.02≦x≦0.6; and M represents at least three elements selected from the group consisting of transition metals other than Zr, Group IIA metals, and Group IIIA metals.
