    Abstract

    Internal damping is investigated for body-centred cubic transition metals (W, Mo, Kb, Ta), using a torsional pendulum, for temperatures between 80° K and 300° K. Cold-worked specimens are found to have a relaxation peak between 200° K and 250° K, which can in general be resolved into several components. By comparison with high frequency measurements, these component peaks are thought to consist of two sets, one due to the relaxation of dislocations (Bordoni peaks) and the other due to the relaxation of the point defects loosely bound to dislocation lines.
