Abstract: The disclination concept can be used to describe rotational substructures developing under large-strain deformation of crystalline metals. The paper presents a TEM microdiffraction method using local misorientation measurements which allows the identification of disclinations. Copper single as well as polycrystals rolled down to 50% and 70% thickness reduction at room temperature were investigated and partial disclinations were found in triple junctions of cell-block boundaries. The power of the partial disclinations lies in the range of 1.5 degrees to 2 degrees, in agreement with theoretical expectations.
