Abstract
Abstract A conventional Ke pendulum was used to investigate the temperature dependence of internal friction for thoroughly annealed samples of Cu30wt.%.Zn. The relaxation peak observed at 300 °C at a vibration frequency of 0.60 Hz was attributed to grain boundary diffusion. The energy activating the process was 1.84 eV and characterized the activation energy for self-diffusion in copper. The relaxation strength showed a strain amplitude dependence, but the activation energy and peak temperature did not. The effects of solute atom concentration, cold work and quenching were also tested.
