Abstract :
The disclination concept can be used to describe rotational substructures developing under large-strain deformation of crystalline metals. The paper presents transmission electron microscopical investigations which allow disclination configurations to be characterized. Copper crystals rolled down to more than 50% thickness reduction at room temperature were investigated and partial disclination dipoles and multipoles were found in nodes of the cell block boundaries.
