General thermodynamic approach to describe the kinetics of thermal effects in high-entropy metallic glasses

A method is proposed to calculate thermal effects induced by the heat treatment of high-entropy metallic glasses within the general thermodynamic approach. The experimental verification of the proposed method shows that the exothermic effect observed below the calorimetric glass transition temperature, the endothermic effect in the glass transition region, and the exothermic effect during the crystallization of a metallic glass can be quantitatively described using the general thermodynamic equation for the change in the entropy of the glass including the diaelastic effect.
