The problem of interrelation between diffusion and stresses is as old as the investigation of diffusion itself. Crack formations during surfaced oxidation, stress-induced diffusion (creep, Gorsky-effect) or macroscpoic deformations of diffusion couples during interdiffusion are well-known classical examples. From a theoretical point of view there are special peculiarities to this problem: the effect of stress fields on diffusion can not be treated as a primary cross-effect, but across the stress-dependence of the chemical potentials. Thus, the results should depend on the density and distribution of sources and sinks, and on the boundary conditions. The latter is related to the fact, that atomic currents are local laws, while elastic interactions have long-range character. Besides the theoretical interest, there is an increasing demand from many practical applications. Especially in thin films and multilayers, the theory and experiments are in close interrelation, and their interference accelerates the efficiency of the research. Investigations of reaction or diffusion-controlled phase formation in massive diffusion samples (shape effects) are also promising.
