Abstract

Solvent-free polyethylene single crystals were plastically deformed by depositing the crystals on carbon replicas obtained from the surfaces of deformed copper single crystals. The observations by transmission electron microscopy suggest that plastic shear parallel to the molecular chains of the polyethylene crystals ([001]-direction) occurs by the movement of dislocations the Burgers vector of which is parallel to the [001]-direction.
