Abstract

Crystallization processes of Se80Te20-x Cdx (x = 0, 4, 8, 10 and 12) alloys at different heating rates have been studied by differential scanning calorimeter (DSC) by using non-isothermal technique. The values of glass transition temperature (T g ) and crystallization temperature (T c ) are found to be composition and heating rate dependence. From the heating rate dependence of glass transition temperature and crystallization temperature, the activation energy of crystallization (ΔE c ), the activation energy for structural relaxation (ΔE t ) and the order parameter (n) have been calculated. It was observed that Se80Te16 Cd4 has a minimum value of activation energy of structural relaxation (ΔE t ), which indicates that this particular glass has a larger probability to jump to a state of lower configurational energy and higher stability in the glassy region.
