Intra-crystalline processes:

1. Dislocation Glide- the glide of dislocations on slip planes generally leads to the reorientation of the crystal lattice.

2. Twinning- twinning inherently involves the reorientation of tabular volumes within a crystal, and as these tabular bodies can widen and coalesce with subsequent deformation, the whole grain can have its lattice orientation altered

3. Kinking- again tabular volumes will be reoriented

4. Rotation Recrystallisation- reorientation of sub-grains as a result of addition of dislocations of like sign to sub-grain boundaries

Inter-crystalline processes

1. Grain Rotation- rotation of a whole grain will necessarily reorient its lattice
