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 (Tg) and crystallization temperature (Tc). 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 Tα, activation energy of crystallization Eα, order parameter n) in non-isothermal mode.
