| Abstract |
The paper surveys various types of dislocation substructure that are created by plastic
deformation in metals. Special reference is made to those substructures that accommodate sharp
misorientations as these are of fundamental importance to the nucleation of recrystallisation.
Several different mechanisms can give rise to high misorientations; these are discussed in terms of
the factors that control them and their relationships to orientation and texture. Different
mechanisms for nucleation of recrystallisation may occur depending on the type of substructure,
allowing some practical control over the final recrystallised texture. |
