Thermodynamic stability of phases and transition kinetics under adiabatic conditions

摘要: A study of equilibrium states a thermodynamic system whose evolution is governed not only by the temperature, but also ordering field carried out. It found that an adiabatically insulated may have new type nonuniform state which inhomogeneous in temperature. The comparison made stability conditions isothermal and adiabatic systems. steady motion interface boundary during first‐order phase transition investigated. shown, depending upon values diffusion coefficients, different regimes can exist. For small thermal diffusivity, temperature final after exothermal be above point. kinetic problem reformulated to dynamical system, numerical procedure solve latter presented. Numerical results are discussed with analytic ones.
