Abstract

The stress distribution and marker movements are simulated for concentration dependent intrinsic diffusion coefficients for the case of stable and unstable Kirkendall marker planes. It is usually assumed is that the marker is fixed to a single atomic plane and indicates and movement of this plane. First we consider this idealized situation than the effect of the marker size is studied. At the beginning of the diffusion process the size of the markers are larger than the size of the diffusion zone. Stress gradients around the marker particles are identified as another source of marker shift. The effect of this additional marker movement on the selection and stability of the Kirkendall marker plane will be discussed.
