On calorimetric study of the fragility in bulk metallic glasses with low glass transition temperature: (Ce0.72Cu0.28)90−x Al10Fex (x = 0, 5 or 10) and Zn38Mg12Ca32Yb18

► Fragility and Kauzmann temperature (Tk) in Ce- and Zn-based bulk metallic glasses were investigated by DSC. ► Zn38Mg12Ca32Yb18 presents a higher kinetic fragility parameter m than (Ce0.72Cu0.28)90−x Al10Fex (x = 0, 5 or 10). ► Kinetic fragility parameter m of bulk metallic glasses increases with the glass transition temperature Tg of bulk metallic glasses.
