摘要：

The Al-Ni-Ce-based amorphous alloys are presented to study compositional dependence of glass-forming ability (GFA), crystallization behavior, thermal stability, medium-range order (MRO) and liquid fragility. The GFA of Al87Ni8Ce5 and Al84Ni8Ce5X3 amorphous alloys ranks as follows: Al84Ni8Ce5Co3 > Al84Ni8Ce5Fe3 > Al84Ni8Ce5Mg3 > Al84Ni8Ce5Cu5 > Al87Ni8Ce5 > Al84Ni8Ce5S3, which have the same tendency with the ratio of the prepeak area to the total area of the main peak in the Xray intensity curve (S-prepeak/S-total). That implies that the GFA has a good relation with the stable MRO structure. Better thermal stability (E-p1) and larger activation enthalpy for the glass transition (Delta H*) corresponds to larger fragility parameter (m). That reflects that the thermal stability of metallic glasses and the stability of supercooled liquids are attributed to the strong-fragile characteristics of glass-forming liquids.
