STUDY OF GLASS TRANSITION KINETICS IN GLASSY ALLOYS OF Se100-x Bix

摘要

Differential scanning calorimetric runs have been taken for Se100-x Bix(x = 0.5, 2.5, 4, 6, 10) glasses under non-isothermal conditions at different heating rates for the thermal study. Well defined endothermic and exothermic peaks are obtained at glass transition (Tg) and crystallization temperature (Tc). The activation energy of glass transition (Eg) has been evaluated on the basis of Moynihan and Kissinger model. The dependence of glass transition temperature on the heating rate β has been reported. The value of (Tc-Tg) and stability parameter S have been calculated for each glassy alloy
