On the nonequilibrium thermodynamics of thermocrystallization motion of inclusions in solids

The methods of nonequilibrium thermodynamics are used to describe the temperature gradientinduced motion of inclusions and the cross effect in solids occurring in the state of premelting. Inclusion motion is caused by a nonuniform disjoining pressure in thin unfrozen interlayers that are formed at a nonuniformly heated inclusion. The cross effect is related to the generation of a local temperature field upon the inclusion motion under the action of an external force in a uniform solid. It is shown that the Onsager relations are valid for the nonequilibrium processes under consideration.
