Determination of kinetics parameters of glass transition in glassy Se and glassy Se_(98)M_2 alloys using DSC technique

摘要

Glassy Se and Se_(98)M_2 (M = Ag, Cd, Zn) alloys are obtained by the melt quenching technique. Differential Scanning Calorimetry (DSC) technique (under non-isothermal conditions) has been applied to see the effects of Ag, Cd, and Zn additives on the glass transition kinetics of Se-rich glassy alloys at different heating rates. The variation of glass transition temperature, T_g with the heating rate, β has been used to investigate the glass transition kinetics. The values of various kinetic parameters such as glass transition temperature, activation energy of glass transition, overall mean bond energy 〈E〉, heat of atomization Hs, bond strength (Se-M) have also been calculated.
