Title: A role of fractions of mobile grain boundaries in secondary recrystallization of Fe-Si steels

Abstract

Grain growth during annealing of polycrystalline materials is influenced by the type of grain boundaries a grain encounters as it grows. Simple computer experiments have been performed to ascertain which type of boundaries are responsible for the abnormal grain growth (AGG) in Fe-3% Si steels. In modeling abnormal grain growth, two different assumptions are used, the first one is that the coincidence site lattice (CSL) boundaries have high mobility and the second is that high energy boundaries are more mobile than other boundaries. The results of the computer experiments support the latter model for abnormal grain growth in Fe-3% Si steels. Finally, the importance of fractions of mobile grain boundaries on the development of Goss texture is discussed.
