Abstract
The solubility coefficient of a substitutional impurity in interstitial solid solutions is calculated within a dynamic model. The presence of an interstitial component increases solubility. In solutions where the interaction between interstitial atoms is negative, a long-range order occurs at interstitial sites at temperatures lower than a certain value. This also causes changes in solubility. An increase in solubility of substitutional impurities is due to ordering at temperatures close to the transition point in the case where the concentration of the interstitial component exceeds 11 at. %. Conversely, solubility decreases due to ordering at lower concentrations. It is shown that an isotopic effect must be observed in solubility of substitutional atoms.
