Nucleation of recrystallization

Nucleation of recrystallization in deformed metals is discussed with a focus on how theories have been achieved from experimental investigations. Suggested nucleation mechanisms and potential nucleation sites are reviewed to gain an overall understanding of the state-of-the-art. Limitations in the applied experimental techniques are discussed followed by an analysis of how newly invented non-destructive 3D techniques have challenged accepted theories which are based on 2D studies. Finally, suggestions for further studies by the novel and improved techniques are presented.
