Title: Binary Ni-Nb bulk metallic glasses

Abstract

We studied the glass forming ability of Ni-Nb binary alloys and found that some of the alloys can be prepared into bulk metallic glasses by a conventional Cu-mold casting. The best glass former within the compositional range studied is off-eutectic Ni{sub 62}Nb{sub 38} alloy, which is markedly different from those predicted by the multicomponent and deep eutectic rules. The glass formation mechanism for binary Ni-Nb alloys was studied from the thermodynamic point of view and a parameter {gamma}* was proposed to approach the ability of glass formation against crystallization.
