Abstract: A novel approach was developed for the problem of mass transfer from a solid inclusion surrounded by the liquid current-carrying metal. The primary mechanism of this process is diffusion under electric current action. The named phenomenon provides more effective diffusion for the alloying process under some conditions than the usual atomic diffusion. Computer calculations and experimental investigations that show this are presented. The systems investigated were the Cusol–Alliq and Nisol–Alliq compositions. The relations between the conductivity of the solid inclusion and the surrounding liquid metal are opposite in the two systems named. Knowledge of the phenomena analysed might be useful for the improvement of alloying technologies.
