Abstract
Nanocrystalline Cu with a grain size of 40-60 nm was prepared by severe pla stic deformation. Active uniaxial tensile deformation of nanocrystalline co pper at a rate of 10(-5) s(-1) was examined iii situ in the column of an el ectron microscope. The deformation was established to be realized mainly by rotation of nanograins and interaction of defects present at grain boundar ies and in adjacent regions.
