| The reactions of interaction between the superdislocations, which accomplish deformation in the basal, prism and pyramidal (I and II types) planes in the single crystal of Ti3Al are examined. Interaction modes, which lead to the formation of dislocation barriers - the microcrack nucleation are established. The force and energy conditions for the formation of microcracks are examined. The classification of the types of microcracks in the dependence on the orientation of the deformation axes of the single crystals is carried out. The regions of stereographic triangle, the characterized by preferred type crack openings are found. |
