An analysis of plastic mismatch, that concentrated mainly on the triple junction area, showed that the defect structure of the compensated triple junctions of real polycrystals, before and after deformation, could be described in terms of disclinations. A tendency to the formation of disclination dipoles in adjacent triple junctions after cold deformation was revealed. An effect was found, of the boundaries which constituted triple junctions, upon Frank vectors. Their magnitude could vary appreciably; depending upon whether the triple junctions did, or did not, contain low-angle boundaries. It was shown that it was sufficient, in order to characterize triple junction defect structures, to determine the matrices of the grain orientations by means of X-ray analysis.
