Peculiarities of Redistribution of Electric and Thermal Fields at the Interface When Passing the Electric Current through the Melt

Abstract

The two-dimensional formulation and the methods of numerical experiments are used to analyze the peculiarities of the redistribution of the lines of a uniform electric field in the volume of molten metal at the interface of nanosized phases with conductivity different from that of the matrix. It is shown that the gradients of the electric and thermal fields are determined by the shape of the phase and the phase conductivity–matrix conductivity ratio. The analyzed surface effects are also determined by the location of the sector of the inclusion surface with the respect to the current lines.
