Role of Bi incorporation on glass transition kinetics in glassy Se78Te20Sn2 alloy

Abstract

In this communication, we report the results of calorimetric measurements on the samples of recently synthesized multi-component glassy alloys of Se78 − xTe20Sn2Bix (0 ≤ x ≤ 6) system. For calorimetric study of glass transition kinetics, differential scanning calorimetry (DSC) technique has been used in non-isothermal mode. Peak glass transition temperature (Tg) is determined using the DSC scans. Kinetic parameters A and B of glass transition are determined using heating rate dependence of Tg. Activation energy of glass transition (Eg) has been calculated using Moynihan and Kissinger methods. Glass-forming ability and thermal stability are also determined using Hurby and Saad–Poulin relations, respectively. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
