摘要

Provided is a Nd-based two-phase separation amorphous alloy by adding an element having a big difference in heat of mixing in a Nd-based alloy with a superior amorphous formability through an inherent characteristic of compositional elements and consideration of thermodynamics, at the time of forming amorphous phase, to thereby enable two-phase separation amorphous alloy during solidification. The Nd-based two-phase separation amorphous alloy which is represented as a general equation Nd100-a-b(TM)a(D)b wherein TM is a transition metal which is a combination of respective one selected from A-B, A-C and B-C when a group of A consists of Y, Ti, Zr, La, Pr, Gd, and Hf, a group of B consists of Fe, and Mn, and a group of C consists of Co, Ni, Cu, and Ag, wherein the content of the element group which constitutes each combination is 5 atomic weight % or greater, and the element selected from each element group is at least one, and wherein D is at least one selected from the group consisting of Al, B, Si and P, and a and b have the range of 20≦a≦80, and 5≦b≦30, respectively, in terms of atomic weight %.
