The problem of the stress-induced ordering of solute atoms, the so- called Zener effect, is considered. In this work the effect of the difference in solute-solvent atom sizes is considered. Starting with this size factor the tensor anelastic strain is computed. Then by the thermodynamic theory for relaxation processes, due Meixner and others, the relaxation strength, is calculated as a function of orientation. The results of the calculation suggest that the size factor is not necessarily the most important contribution in determining the relaxation strength. It is suggested that electronic effects may be more significant.
