摘要
In this paper, we have incorporated Cd, In, and Sb in glassy Se80Te20 alloy to see the metal-induced effect of these additives on its glass network and kinetic properties. Specifically, we report results of systematic calorimetric measurements to study the glass transition kinetics. The glass transition behavior of glassy Se80Te20 and glassy Se80Te10M10 (M = Cd, In, Sb) alloys has been analyzed by differential scanning calorimetric technique at various heating rates. The activation energy (E (g)) of glass transition was determined using different kinetic models. Analysis of experimental data reveals that E (g) varies with the additive elements. The value of various kinetic parameters such as thermal stability, Hruby number, and fragility index has been calculated in non-isothermal mode.
