We report on the thermal analysis of As₄₀Se₄₀Ag₂₀ glass using experimental and theoretical methods. The XRD analysis revealed the amorphous-crystalline transition in the annealed As₄₀Se₄₀Ag₂₀ glass. Two overlapped crystallization peaks were observed, which are analyzed using different models. The activation energy of glass transition exhibited a change with conversion fraction χ_g. The fragility index showed that As₄₀Se₄₀Ag₂₀ material belongs to strong glass-forming liquids. The kinetic transformation parameters were obtained by the theoretical developed (TDM) and Johnson–Mehl–Avrami (JMA) model. The crystallization activation energy varied with the conversion fraction. According to the average values of kinetic exponent parameters (n and m obtained by TMD and JMA models) two and three crystal growth process with heterogeneous nucleation of the studied composition are observed. The experimental results were compared with calculated ones by different models.
