Abstract

The effect of Al addition on the local structure and the thermal stability in the Zr-Ni-based metallic glass is investigated. It is well known that Al is a very effective element on the enhancement of glass-forming ability (GFA), i.e., stability of supercooled liquid state in the alloy system. We have found that the dominant local structure is icosahedral-like in the Zr70Al10Ni20 metallic glass and the tetragonal Zr2Ni-like local in the Zr70Ni30 amorphous alloy. It is concluded that the change in the dominant local structure contributes to the enhancement of the stability of supercooled liquid state in the alloy.
