Abstract
The strain amplitude‐dependent dislocation damping of pure (∼5 ppm interstitials) tungsten samples has been measured as a function of temperature from −190° to +100°C. The data cannot be interpreted in terms of the sample thermally activated breakaway theory of Friedel. The data gives the wrong stress dependence and unreasonably low activation energies.This publication has 6 references indexed in Scilit:
