摘要：

The crystallization kinetics of glassy Se98Ag2 alloy is studied at different heating rates (5, 10, 15, and 20 K min(-1)) using differential scanning calorimetric technique. Endothermic and exothermic peaks are obtained at glass transition (T-g) and crystallization temperature (T-c). Four iso-conversional methods (Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), Tang and Straink) were used to determine the various kinetic parameters (crystallization temperature T-alpha, activation energy of crystallization E-alpha, order parameter n) in non-isothermal mode.
