Zener damping peaks which appear in Fe-(6.4∼11.8)at%Si and Fe-(10.5∼24.2)at%Cr poly-crystalline alloys have been investigated in detail. The magnitudes of the relaxation strength Δ_M of these alloys, combined with those of the Fe–Al alloys investigated previously, have been compared with both Zener’s solute pair reorientation theory and LeClaire and Lomer’s directional short-range order theory. It has been shown that Δ_M is closely related with the deviation of lattice parameter from Vegard’s law on alloying rather than with the size factor, as predicted by Nowick and Seraphim on the basis of Zener’s theory. The difference of the relaxation strength among the ferrous alloys appears to be reasonably explained by their model. The validity of LeClaire and Lomer’s theory has also been examined briefly. Using the interatomic potentials given by Leamy, the theory accounts for Δ_M in Fe–Al alloys to some extent.
