Abstract

ABSTRACT: In this communication, we report the results of calorimetric measurements on the samples of recently synthesized multi-component glassy alloys of Se78 − x Te20 Sn2 Bix (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 ( T g ) is determined using the DSC scans. Kinetic parameters A and B of glass transition are determined using heating rate dependence of T g . Activation energy of glass transition ( E g ) has been calculated using Moynihan and Kissinger methods. Glass-forming ability and thermal stability are also determined using Hurby and Saad–Poulin relations, respectively.
