    Experimental and theoretical studies on the effect of substitutional solutes on the Snoek relaxation of interstitial solutes in body-centered-cubic (bcc) metals are reviewed. The presence of a small amount of alloying element (M) gives rise to additional components, which often lead to a complex damping spectrum. The origin of the effect is the interaction between the substitutional and interstitial solute atoms, or s-i interaction. Experimental findings on the s-i interaction in Fe-M-(C, N) and (V, Nb, Ta)-M-(O, N) systems are presented, and theoretical studies on the relaxation mechanism are summarized. Recent advances in experiment and theory are briefly described, followed by suggestions for future studies.
