Internal friction peaks, which appear in cold‐worked metals above the Bordoni peak temperature, are considered, on the basis of a point defect‐associated dislocation model, to be due to relaxation. Calculated data regarding activation energies, pre‐exponential factors, and relaxation strengths are compared with experimental data of ten metals, an alloy, and an ionic crystal. These data thus gives experimental values for the binding energy between dislocations and the point defects concerned (e.g. vacancies, interstitial atoms, impurity atoms, etc.).
