Physical aging effects in selenide glasses accelerated by highly energetic γ-irradiation
Source abstract
Abstract
Effect of 60 Co γ-irradiation on As-Se glasses stored for 20 years and subjected to saturated natural physical aging is studied using differential scanning calorimetry. It is shown that γ-irradiation activates further physical aging, which leads to an increase in glass transition temperature and endothermic peak area near glass transition region for As x Se 100-x samples with x < 30. The observed changes are associated with additional structural relaxation of radiation-modified glass network.
