The chemical short range order of Al Fe Ce amorphous alloy was studied by means of X ray diffraction(XRD) and differential scanning calorimetry(DSC). It is found that the prepeak position in X ray diffraction intensity curve shifts to higher angles as the content of Fe increases, but it shifts to smaller angles as the content of Ce increases. The crystallization character of the amorphous alloy changes with the variation of the content of Fe and Ce. Ce can improve the interaction between atoms and the capacity of compound formation, so it is favorable to Al based glass formability.
