Abstract

La présente invention concerne un aillage amorphe de résistance améliorée à la fragilisation lors d'un traitement thernique. La présente invention décrit une amélioration dans la résistance à la fragilisation qui survient lors du traitement thermique d'alliages métalliques amorphes contenant du fer, du nickel, du cobalt et/ou du chrome lorsque les températures des traitements thermiques sont comprises entre environ 200 et 350 degrés C. Cette amélioration est obtenue notamment en incluant du bore ou du bore plus ou moins un élément métalloïde tel le carbone, le silicum ou l'aluminium en quantité comprise entre environ 15 et 25 % d'atomes du composé allié. Application à l'élaboration d'un alliage métallique amorphe, amorphe à au moins 50 % conservant une bonne ductifité et une charge limite de rupture importante après un traitement thermique à une température comprise entre environ 200 et 350 degrés C.
