The effects of chemical short-range order on the glass forming ability of Al-Zn-Ce alloy are studied by X-ray diffraction （XRD） and different scanning calorimetry （DSC）. The results show that Ce addition can promote the interatomic chemical combination of Al-Zn-based alloy to improve the formation probability of compounds and stop phase separation. The prepeak in XRD patterns indicates that strong chemical short-range order exists in Al-Zn-Ce alloy, as can improve the glass forming ability of Al-Zn-Ce alloy.
