Abstract
Youngʹs modulus of copper polycrystals with an ultrafine-grained structure synthesized by two independent methods (compacting and heavy plastic deformation) has been measured within a temperature range from 20 to 200–300°C. It has been concluded that there is a component of the Youngʹs modulus softening which is peculiar to metals with nano- and submicrocrystalline structures, irrespective of the presence of porosity.
