Influence of annealing temperature before cold rolling and Cu content on the secondary recrystallization in nitrided Fe-3% si alloy

Abstract Secondary recrystallization structures of 100% were obtained from nitrided primary specimens with different annealing temperatures before cold rolling and with various Cu contents. However, magnetic induction B 10 varied between 1.58 and 1.95 T. The evolution mechanism of the wide range of B 10 was interpreted due to a change in the types of grain boundaries that became specifically mobile during secondary recrystallization.
