Abstract:
It is normally assumed in the literature that the Snoek relaxation in b.c.c. metals leads to internal friction peaks of the Debye type at very low interstitial contents. By means of a new measuring technique, however, it is shown that this is not generally the case. This technique allows simultaneous measurement of the internal friction vs. the temperature and of its derivatives with respect to the temperature and frequency. The data indicate that a distribution of relaxation times is present even for concentrations of a few hundred atomic parts per million. Some results for the Snoek relaxation in niobium are discussed in detail, showing that the parameters of the distribution change with the concentration of interstitials and the temperature. © 1994.
