OUTLINE Recrystallization What is it How is it usually treated Importance of local misorientation/strain gradients on “nucleation” First stages of recrystallization; how can we investigate the “nucleation” Rapid heat treatments What are they What can we expect from them Recrystallization in metals Modeling Conclusions-Future work 2
Recrystallization What is it Fe E =E stored =~100J/mol Deformation Heat Recrystallization (development of new strain free grains) Recovery (rearrangement of dislocations in sub grains) 3
