Disclosed is an amorphous alloy superior in processability which has a composition represented by the general formula: XaMbAlc Wherein: X is one or two elements of Zr and Hf; M is at least one element selected from the group consisting of Ni, Cu, Fe Co and Mn; and a, b and c are, in atomic percentages: 25 </= a </= 85, 5 </= b </= 70 and 0 < c </= 35, preferably 35 </= a </= 75, 15 </= b </= 55 and 5 </= c </= 20 and more preferably 55 </= a </= 70, 15 </= b </= 35 and 5 </= c </= 20, the alloy being at least 50% (by volume) composed of an amorphous phase. Since the amorphous alloy is at least 50% by volume amorphous and can be present in a supercooled liquid state in a wide temperature range, it has a greatly superior processability together with high levels of strength, thermal resistance and corrosion resistance which are amorphous characteristic. |
