Abstract
The crystallization kinetics of Se100-xBix ( x = 0, 0.5, 2.5, 5 and 10) glassy alloys at different heating rates ( 5, 10, 15 and 20 K/min) have been studied by using Differential Scanning Calorimeter. The glass transition temperature at different heating rates and structural changes during glass transition have been determined from an empirical relation. The glass transition temperature ( T-g), the crystallization temperature (T-c), the order parameter (n), the activation energy of crystallization (Delta E-c) and the enthalpy released (Delta H-c) have been calculated and their compositional dependence has been discussed in terms of the structure of Se-Bi system. The results of crystallization have been discussed on the basis of Kissinger's approach and Matsusita's modified expression for non-isothermal crystallization.
