Electric fields associated with moving phase boundaries during martensitictransformation

Phase transformations in metals are considered in terms of non-equilibrium continuum thermodynamics. The evolution of a heterophase system in thermal and electric fields is described by a self-consistent set of differential e quations. Special attention is paid to the thermoelectric properties of pha se boundaries. A one-dimensional model for uniform translational motion of a plane interface is developed, the spatial distributions of temperature an d electric charge, current and potential are calculated.
