Thermal effects in dynamics of interfaces

摘要

Dynamical Ginzburg-Landau theory is applied to the study of thermal effects of motion of interfaes that appear after different phase transitions. These effects stem from the existence of the surface thermodynamic properties and temperature gradients in the interfacial transition region. Thermal effects may be explaned by the introduction of a new thermodynamics force exerted on the interface, called here Gibbs-Duhem force, and the internal energy density flux through the interface. The evolution equations for the interfacial motion are derived. For the experimental verification of the thermal effects during continuous ordering the experssion is derived for the amplitude of temperature waves
