abstract


The thermodynamic model based on CALPHAD methods for the theoretical evaluation of the activation energy of the conversion of a multicomponent amorphous phase in submicron and nanocrystalline phases and for calculation of heat released at the same time is proposed. It is shown that the enthalpy of nonequilibrium phase transition stored in an amorphous powders can be considered as a new technological parameter of the crystallization process of the amorphous phase, which can be used for control of structure and properties of crystallizing materials, for improve of energy efficiency of consolidation of amorphous dispersions into macro volume as well as for formation of different types of multifunctional coatings and products.
