摘要
On purpose to verify the applicability of models of solute atoms interaction in b.c.c. metals internal friction due to "diffusion under stress" of interstitials was calculated. For interstitial-interstitial (i-i) and interstitial-substitutional (i-s) interaction a strain-induced interaction model with additional Coulomb repulsion in (i-i) case and additional "chemical" interaction in (i-s) case was used. Calculations were made with concrete values of interaction energies. It was shown that the Snoek peak's shape in Ta-O was very sensitive to the (i-i) potential details. Computer simulation showed that the broadening of the maximum in experiments is caused by appearance of short-range order due to long-range (i-i) interaction and the Coulomb repulsion is important up to the third coordination shell. The used (i-i) interaction model is applicable to Ta-O solid solution. In the (i-s) case the influence of s-atoms on the Snoek relaxation due to O and N in V, Nb and Ta and N and C in alpha-Fe was calculated by using Koiwa's theory. On the whole there is a good agreement between experimental and calculated spectra for Nb, V, Ta and no agreement for alpha-Fe. Thus the used (i-s) interaction model is only applicable to V, Nb and Ta solutions.
