Abstract
Rheological and relaxational properties of distillate and technical beryllium were studied. It was shown that strengthening and thermal softening processes in nanocrystalline beryllium significantly differ from the same processes in distillate and technical beryllium. Thermal softening in distillate and technical beryllium takes place only at the holding time between deformations; in case of nanocrystalline beryllium, thermal softening takes place during the deformation process. It was considered that beryllium plastic deformation at 400–500°C involves an additional mechanism of deformation and stress relaxation: twinning; this mechanism increases the metal plasticity.
