New Method of Phase Transformations Calculation in Metals with Structural Features of the Initial and New Phases

Abstract:

It is specified an interrelation between thermal effects in metals phase transformations and changes in structural parameters (coordination number) of the initial and new phases. It is offered the analytical dependences for calculation of the binding energy and atoms coordination numbers, the metals heat of formation, temperature and thermal effects of phase transitions in metals. It is analyzed the energy parameters of the Periodic System elements considering the type of their crystal lattices. By calculation it is estimated structural parameters of liquid and solid phases, thermal effects and the evaporation temperature of crystallization and polymorphic transformation, and energy formation for 55 elements, for which the literature contains reliable experimental data.
