Softening of the elastic modulus in submicrocrystalline copper

Softening of the elastic modulus in submicrocrystalline copper

Young's 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 Young's mod...

Zusammenfassung:Young's 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 Young's modulus softening which is peculiar to metals with nano- and submicrocrystalline structures, irrespective of the presence of porosity.
