Disclosed is an amorphous alloy having superior processability which has a composition represented by the general formula: XaMbAlc wherein: X is at least one element 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 characteristic of amorphous alloys.

Alliage amorphe dont l'aptitude au traitement est supérieure et dont la composition est représentée par la formule générale suivante : XaMbAlc où X est au moins un élément de Zr et de Hf; M est au moins un élément choisi dans le groupe Ni, Cu, Fe, Co et Mn et a, b et c sont, en pourcentage atomique 25 ~ a ~ 85, 5 ~ b ~ 70 et 0 < c ~ 35, préférablement 35 ~ a ~ 75, 15 ~ b ~ 35 et 5 c ~ 20, l'alliage étant composé au moins à 50 % (en volume) d'une phase amorphe. Comme l'alliage amorphe est composé au moins à 50 % (en volume) d'une phase amorphe et qu'il peut être présent à l'état liquide en surfusion dans une plage de températures étendue, son aptitude au traitement est grandement supérieure et sa résistance mécanique, sa résistance thermique et sa résistance à la corrosion sont élevées.
