The application of the random cooperative strain interaction model to the description of the interaction of interstitial solute atoms in body-centered cubic metals (Snoek relaxation) was considered. By applying this model in the mean-field approximation, and by using the so-called Onsager correction, a new formula was derived which described the mechanical after-effect (creep). The results made it possible to formulate a hypothesis in which, to a first approximation, the interaction of interstitial solute atoms in body-centered cubic metals did not depend upon the solvent lattice or even perhaps upon the type of solute atom.
