A technique was developed for the determination of the components of the Frank vector for disclinations in the triple junctions of real polycrystalline aggregates. By using this technique, it was shown that real polycrystals in the as-prepared condition contained junction disclinations which had been produced during the thermomechanical history of the polycrystals. The formation of disclination-dipole configurations in adjacent triple lines was a result of an evolution of the initial junction disclination network. The type of boundaries which formed junctions affected the strength of the Frank vector of a junction disclination.
