Abstract

There are strong experimental evidences that considerable stress develops in mutual diffusion. The non-local character of the stress equilibrium also leads to strong dependence on the sample geometry. Stress effects are expected to be stronger in cylindrical and spherical samples having closed geometry than in the usually studied planar geometry. We will give an overview of the interrelation of stress and diffusion, and introduce equations of the theoretical model describing material transport, stress development and convective matter transport. These differential equations can be integrated only numerically. Simulation results and experimental findings will be presented for planar and cylindrically bent diffusion couples.
