Crystallisation kinetics and thermal stability analysis of Se82-xTe15Sn3Sbx (0≤x≤6) glassy alloys

This paper reports the results of study of crystallization kinetics and thermal stability in Se82-xTe15Sn3Sbx (0 ≤ x ≤ 6) glassy alloys. The alloys were analysed using DTA (differential thermal analysis) technique under non-isothermal conditions at heating rates of 5, 10, 15, 20 K/min, Activation energy of glass transition has been evaluated using Kissinger and Moynihan methods while Matusita, Kissinger and Augis and Bennett approaches has been employed to study the crystallization mechanism. Thermal stability and glass forming ability for all compositions has been analysed in terms of reduced glass transition temperature and Hruby's parameter.
