摘要：

Effect of long-term physical ageing (similar to 18-21 years) in vitreous germanium selenides is studied using differential scanning calorimetry method. It is compared with short-term physical ageing observed in these glasses earlier. Low compositional limit of the non-ageing ability determined using old samples coincides with the onset of reversibility window obtained using short-term aged samples of Ge-Se system by temperature modulated differential scanning calorimetry technique.
