  • Nd-based two-phase separation amorphous alloy
    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
