Available in PDF, EPUB and Kindle. Book excerpt: The question of the interrelationship between diffusion and stress is almost as old as the investigation of diffusion itself. Nowadays, the study of various diffusion and solid-state reaction processes in thin films and multilayers is a vital area of research activity in which, inevitably, diffusion-induced or thermal stresses are of primary importance.

Book excerpt: The problem of the interrelationship between diffusion and stresses is as old as the investigation of diffusion itself. Crack formation during surface oxidation, stress-induced diffusion (creep, Gorsky-effect) and the macroscopic deformation of diffusion couples during interdiffusion are well-known classical examples. From a theoretical point of view, there are special peculiarities attached to this problem: the effect of stress fields upon diffusion cannot be treated as a primary cross-effect, but instead links the stress dependencies of the chemical potentials. Thus, the results should depend upon the density and distribution of sources and sinks, and upon the boundary conditions. The latter expectation is related to the fact that atomic currents are local phenomena, while elastic interactions have a long-range character. In addition to the theoretical interest, it has an increasing importance in many practical applications. In thin films and multilayers, theory and experiment have an especially close relationship and their interaction increases the efficiency of the research. Investigations of reaction- or diffusion-controlled phase formation in massive diffusion samples (shape effects) also appear to be promising.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of a general state of stress on swelling has been considered in a theoretical void growth model. Angular-dependent loop growth has been incorporated into the model in order to include the effects of shear stress. It has been found possible to consider the effects of stress on void and loop growth as a relatively simple deformation process. We define the stress effect as follows: where (d?i/dt)?=0 is the strain rate associated with the isotropic swelling that would occur in stress-free conditions. For an applied stress having both hydrostatic and shear components, the hydrostatic component provides a driving force for isotropic volume swelling and the shear component causes a shape change. The total deformation process (stress-induced volume increase and shear) may be represented by the relation: where the ?'s are applied tensile stresses and the i, j, K are the principal axes. K and ? are two material parameters that depend upon microstructure (dislocation density, void number density, and void size) but do not depend upon flux. K depends strongly on temperature whereas ? is independent of temperature. The extent to which plastic flow must accompany stress-assisted swelling is governed by the parameter ?. As ? approaches 1/2, the deformation process becomes pure shear. It is found that the value of ? is bounded and lies between -1/3 and +1/2. Thus, except under the application of purely hydrostatic stress, stress-assisted swelling cannot be completely shear-free. When transmission electron microscopy (TEM) data for neutron-irradiated solution-treated Type 316 stainless steel were used, the values of ? were found to lie between 0 and 0.5. For cold-worked steels, ? is expected to lie in the upper part of the range just given. The significance of the present results becomes evident in the analysis of fuel pin profiles. For isotropic swelling with no plastic flow, the fractional change in fuel pin diameter is 1/3 the fractional isotropic volume change. However, for stress-assisted swelling, the relation may be much different and depends upon the parameter ?. For a biaxial stress state of the type that occurs in pressurized cylindrical tube, for example, ? D/D ? 0.7 when ? = 0.1, whereas ?D/D? 1.4 ?V/V when ? = 0.3.
