“…With the obtained data of ω i ω 2 and g p , B eff can be calculated at temperatures for which no experimental values exist. In table 2, B eff values calculated for solute diffusion in the Zr/V [8], V/Co [22], Zr/Mn [21,22] and V/Zr [9] systems are shown. Table 2 also lists the various parameters which were evaluated by fitting to equation (41) of the experimental B values.…”

In this paper the solute and solvent enhancement factors in a hypothetical body centered cubic (b.c.c) structure having fourteen first nearest neighbors are calculated by using a statistical model for diffusion in dilute alloys. Inherent to the model is the assumption of the equality of the first and second nearest neighbor jump distances, since in the b.c.c structure the difference between these distances, respectively, is only ∼13.5%. The number of parameters required for fitting to evaluate the enhancement factors (b and B) is substantially reduced in comparison to existing models and therefore fewer experiments are necessary. Correlation effects are implicit in the calculated values of b and B. The results of the fitting provide values for the frequency ratios, the additional energies required to form a vacancy in the vicinity of a solute and for the binding energies between solute pairs, i.e., between the reference and tracer solute. Values of b and B in several dilute alloys were calculated at different temperatures. In general there is a good agreement between experimental and calculated values of b and B in the alloys tested. The equations for b and B can be used for temperatures where no experimental data exist.

A reformulation of the solute/solvent diffusion enhancement problem is discussed by introducing a new set of two empirical parameters. A comparison with experimental data, both for solvent and solute enhancements, shows good agreement. A constant u is introduced relating the preexponential factor and the activation energy in the Arrhenius equation for the diffusion coefficient. This constant is attributed to the solute/solvent enhancement-reduction transition temperature.
