Abstract In this paper of the measurements internal friction of iron whiskers are described; a torsion pendulum was especially adapted for this purpose. It was found that the internal friction of whiskers having larger diameter than 10 μm was usually amplitude dependent. This amplitude dependence approximatively fits the Granato-Lücke theory of dislocation damping. The effects of plastic deformation and its recovery in iron whiskers were also studied. The results and their discussion lead to the assumption that during the recovery an important role is played either by the interaction of dislocations with vacancies, or by the interaction of dislocation dipoles with the impurity atoms.
