Abstract
Peculiarities of the splitting of grain boundary disclinations in poly crystalline and nanocrystalline solids are examined theoretically. The three basic variants of such a splitting (planar splitting, threefold star splitting, circle splitting) are considered with special attenti on to calculations of the energetic characteristics of these splitting processes. It is shown that the planar splitting decreases the probab ility of microcrack generation at grain boundaries.
