Determination of kinetics parameters of glass transition in glassy Se and glassy Se sub(98)M sub(2) alloys using DSC technique

Glassy Se and Se sub(98)M sub(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 glass...

Summary:Glassy Se and Se sub(98)M sub(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 sub(g) with the heating rate, beta 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 , heat of atomization H sub(S ), bond strength (Se-M) have also been calculated.
