Boundary dislocation structure of crystalline composites

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

  1. 1.

    A study has been made of the dislocation structure of the boundary regions in crystalline composites formed by solid-phase intergrowth of individual single crystals. It has been established that the dislocation structure depends on the conditions under which the intergrown composites are formed. It has been demonstrated that crystalline composites can be obtained without increasing the density of the dislocations near the boundary, and the strength along the boundary remains equal to the strength of the bulk material.

  2. 2.

    It has been established that the intergrowth boundary of a crystalline composite consists of two dislocation networks. One of these is a network of immobile dislocations; the other is the usual subboundary that may shift from its original position and thereby accomplish splitting of the intergrowth boundary into two structural defects.
