PROBLEM TO BE SOLVED: To produce an amorphous alloy described in U.S. Pat. No.5, 735, 975 by using commercially available raw materials and a conventional vacuum diescast apparatus. SOLUTION: The amorphous alloy substantially comprises Zr and/or Hf of about 45 to 65 atomic %, Ti and/or Nb of about 4 to 7.5 atomic %, and Al and/or Zn of about 5 to 15 atomic %, and the balance comprising a metal selected from the group consisting of Cu, Co, Ni, up to about 10 atomic % Fe, and Y intentionally present in the alloy compositions in an amount not exceeding about 0.5 atomic %, for example, about 0.2 to 0.4 atomic %. The alloy has an alloy bulk oxygen concentration of at least about 1,000 ppm on atomic basis. COPYRIGHT: (C)2004,JPO
