An elastic creep and stress relaxation of 99.96. polycrystalline copper have been inverstigated in the temperature range of 135-380- The activation energy associated with the creep was found to be 25>000-2000 calories per mole. It is much smaller than the activation energy for the volume self-diffution and is close to the activation energy for the grain boundary self-diffusion of copper. The mechanism of anelastic creep of polycrystalline copper at higher temperatures may thus be considered to be similar to...
