Models of Interdiffusion in a Polycrystalline Alloy: Kirkendall Effect versus Non-Equilibrium Vacancies and Backstress

Abstract:

Article Preview

In order to study evolution of the concentration profiles and markers velocities in various time and space scales quasi-one-dimensional model of interdiffusion in a polycrystalline alloy is proposed considering non-equilibrium vacancies and the Kirkendall effect. Sinks/sources of vacancies are assumed to be concentrated mainly at the moving grain boundaries. This model simultaneously takes into account the movement of grains and changes of grain sizes.
