摘要：

Effect of Co-60 gamma-irradiation on physical ageing in binary GexSe100-x glasses (5 <= x <= 27) is studied using conventional differential scanning calorimetry method. It is shown, that high-energy irradiation leads to additional increase in the glass transition temperature and endothermic peak area near the glass transition region over the one induced by isochronal storage of these glasses at normal conditions. This gamma-induced physical ageing is shown to be well-pronounced in Se-rich glasses (x < 20), while only negligible changes are recorded for glasses of 20 <= x <= 27 compositions. The effect under consideration is supposed to be associated with gamma-activated structural relaxation of the glass network towards thermodynamic equilibrium of supercooled liquid.
