Abstract

Schmitz et al. [Acta Materialia 57 (2009) 2673] showed experimentally that stress effects significantly influence the intermixing rate but surprisingly the parabolic growth rate is preserved. The influence on the intermixing rate was interpreted as a switching between the Darken and Nernst-Planck regimes caused by the diffusion-induced stress. We analyse theoretically how the stress field shifts the system from the Darken to the Nernst-Planck regime, why stress relaxation is not observed even though expectedand why the diffusion kinetics is not influenced by the developing stress field.
