Claim Text:
1. A Nd-based two-phase separation amorphous alloy for magnetic material applications which is represented as a general equation Nd 100-a-b-c (TM1) a (TM2) b D c consisting of: TM1 being Fe, and TM2 being Ag or Ag and Cu, wherein the content of each of said TM1 and TM2 does not exceed 50 atomic weight %, wherein D is Al, a and b have the range of 60≦a+b≦70 and 5≦c≦20 in terms of atomic weight %, wherein said TM1 and TM2 exhibit positive enthalpy of mixing causing a miscibility gap between first constituting elements of Nd-TM1-D and second constituting elements of Nd-TM2-D, and wherein the alloy has a two-phase separation amorphous microstructure (DA) with a first and a second phase nano-scale microstructures formed during solidification in correspondence with said miscibility gap between said first and second constituting elements, and exhibits two super-cooled liquid regions with respect to said first and second amorphous phases to enable a multi-stage deformation behavior.
