Abstract
Transition kinetics study is an important field in the analysis crystallization and glassy behavior. Crystallization and glass transition kinetics of Te(1−x) (GeSe0.5)Scx (x = 0.1) glass alloy have been reported using theoretical and experimental methods. Melt-quench technique was used for preparing the samples. Differential scanning calorimetry (DSC) has been done at various heating rates (5, 10, 15, and 20 K/min). Glass transition activation energy showed a change with a fraction of conversion \({\chi }_{\text{g}}\). Activation energy Et has been calculated using different models: Moynihan and Kissinger models. Though, obtained \({E}_{t}\) values were evaluated by using the Moynihan model agreed by the Kissinger method used for attaining decomposition reaction activation energy. Iso-conversional methods have also been used for evaluating Et such as Kissinger–Akahira–Sunose (KAS), Flynn–Wall–Ozawa (FWO), and Tang methods. Results attained experimentally were compared by the calculated values from different models, Johnson–Mehl–Avrami (JMA) and theoretical method developed (TMD) model, and the TMD model was noticed to satisfy with experimental values.
