Abstract [en]

In order to learn more about the atomic mechanisms of the migration of phase interfaces one should study the kinetic equations. They are based on the driving forces which can be obtained from the deviation from local equilibrium at the migrating interface. The thermodynamic and mechanistic background of the deviation from local equilibrium will be described and illustrated with molar Gibbs energy diagrams. It will be discussed how the flux equations for individual components can be formulated in order to represent various causes of friction. The discussion will be based on the sharp interface model but its shortcomings will be emphasized.
