Interaction between a Dislocation and its Surroundings,ear in the form of an external stress field acting on the dislocation. The forces which can move the dislocation originate from this stress field. In this chapter a representation of the stress field will first be given and afterwards the forces on a dislocation will be discussed.

The Interaction of Dislocations,ocation makes it possible now to understand the interactions between two dislocations. This leads to the study of dislocation reactions, i.e. the nodes formed by dislocations. At the end of the chapter dislocation reactions in special crystal structures will be investigated.

,Dislocation Networks—Subgrain Boundaries,xt, the word “slightly” means that the two crystals are practically in register over areas which are large compared to the unit cell, and that only occasional corrections are needed in the form of dislocations. Such a boundary, consisting of a network of discrete dislocations, is termed a “subgrain boundary”.

Applications of the 0-Lattice Theory, ordering into the interpenetrating lattices. The next step is the choice of the boundary. Once the boundary is chosen, the atoms will occupy, on the one side of the boundary the positions of crystal 1, and on the other side those of crystal 2. The boundary itself is a remnant of the 0-lattice structure.

About 1961, the work of the author, essentially based on the fundamental work of Professor F. C. Frank, started to branch away from the main flow of

The diamond structure prevails in the field of semiconductors, while (the hexagonal) graphite is important as a moderator material in reactor technology and as a precipitate in cast-iron.
