| Abstract | ||||
| Differential scanning calorimetry (DSC) of two amorphous alloys of the ternary isoelectronic system Se60 S40-x Tex (x = 15 and 25) at different heating rates are reported and discussed. Characteristic temperatures, glass transition temperature (Tg), crystallization temperature (Tc) and melting temperature (Tm) and the glass forming tendency (Kgl), have been estimated. The kinetic parameter (Ec) has been determined using non- isothermal multi-scan technique of Kissinger approach. The calculated order of reaction (n) indicate that bulk crystallization with one-dimensional growth occurs for these glasses. Cyclic scanning technique has been used to demonstrate the structural change during two consecutive heating-cooling cycles. | ||||
