Mixed-alkali effect was studied by irradiating (15-x)Na2O .xK2O.85SiO2 glasses with electrons and observing the following glass response expressed through volume changes measured with AFM.Low irradiation doses showed the volume compaction while at high doses most of glasses show volume expansion. Alkali depletion from the surface layer is explained in terms of negative correlation among the element specific migration path.
