Applicability of Augis–Bennett relation for determination of activation energy of glass transition in some Se rich chalcogenide glasses

Abstract

The present work reports the results of non-isothermal DSC measurements on some Se-based ternary glasses for evaluation of activation of glass transition. The activation energy of glass transition (Eg) is determined using Augis–Bennett's relation, which is basically derived for amorphous to crystalline phase transition. Moynihan's relation which is derived on the concept of thermal relaxation and is basically used for glass transition is also used for determination of Eg values. We have observed that Eg values obtained from Augis–Bennett's relation are in admirable agreement with the Eg values which are obtained using Moynihan's relation.
