Abstract
Submicrometre-grained (SMG) copper with a mean grain size of 0.2 mum w as produced by severe plastic deformation. In the samples obtained and annealed, the strain amplitude dependences of the internal friction a nd shear modulus defect were studied and the microhardness and tensile strength were measured. A close correlation of elastic and inelastic parameters with grain boundary states is shown. An analysis of the nat ure of the combination of high damping and strength properties in SMG copper is given.
