Abstract

An amorphous alloy having a composition represented by the general formula: X a M b Al c (wherein X represents at least one element selected from the group consisting of Zr and Hf, M represents at least one element selected from the group consisting of Ni, Nb, Cu, Fe, Co, and Mn, and a, b, and c represent such atomic percentages as respectively satisfy 25≦a≦85, 5≦b≦70, and 0<c≦35) and containing an amorphous phase in the range of 50-100% in a volumetric ratio contains hydrogen incorporated therein. Preferably the hydrogen is present in the amorphous alloy in an amount of 0.005-10% of the amorphous alloy in a weight ratio.

Claims

exact text as granted — not AI-modified
1 . An amorphous alloy having a composition represented by the following general formula and containing an amorphous phase in a volumetric ratio of 50-100%, the improvement which comprises hydrogen incorporated therein:  
       X a M b Al c    
     wherein X represents at least one element selected from the group consisting of Zr and Hf, M represents at least one element selected from the group consisting of Ni, Nb, Cu, Fe, Co, and Mn, and a, b, and c represent such atomic percentages as respectively satisfy 25≦a≦85, 5≦b≦70, and 0<c≦35.  
   
   
       2 . The amorphous alloy according to  claim 1 , wherein said hydrogen is present in said amorphous alloy in an amount of 0.005-10% of said amorphous alloy in a weight ratio.
