  • Patent number: 9347117
    Abstract: 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.
    Type: Grant
    Filed: February 10, 2009
    Date of Patent: May 24, 2016
    Assignee: Yonsei University
    Inventors: Eun Soo Park, Hye Jung Chang, Do Hyang Kim, Eun Young Jeong, Jin Kyu Lee, Hwi Jun Kim, Jung Chan Bae
  • Patent number: 8016955
    Abstract: Disclosed is a magnesium based amorphous alloy having a good glass forming ability and ductility. The Mg based amorphous alloy has a composition range of Mg100-x-yAxBy where x and y are respectively 2.5?x?30, 2.5?y?20 in atomic percent. Here, A includes at least one element selected from the group consisting of Cu, Ni, Zn, Al, Ag, and Pd, and B includes at least one element selected from the group consisting of Gd, Y, Ca, and Nd.

  • Patent number: 7582173
    Abstract: Disclosed is a single-phase amorphous alloy having an enhanced ductility. The single-phase amorphous alloy has a composition range of A100-a-bBaCb where a and b are respectively 0<a<15, 0?b?30 in atomic percent. Here, A includes at least one element selected from the group consisting of Be, Mg, Ca, Ti, Zr, Hf, Pt, Pd, Fe, Ni, and Cu. B includes at least one element selected from the group consisting of Y, La, Gd, Nb, Ta, Ag, Au, Co, and Zn. C includes at least one element selected from the group consisting of Al, In, Sn, B, C, Si, and P.
