Modelling grain growth in the presence of Zener drag: application for Fe-3% Si

摘要

The presence of AlN and MnS inhibitors in Fe-3% Si sheets, grade Hi-B, permits the development of Goss texture by the sudden and rapid growth of small grains possessing a {110}〈001〉 orientation. This behavior is not in good agreement with the classical laws of secondary recrystallization. In the present study, first the minimum critical radius of the grain which is susceptible to growth is determined in relation to orientation and grain size neighborhood. Moreover, the necessity to define a maximum critical radius for the neighborhood is established. Consideration of these two radii permits the exploration of possible growth sequences for small grains.
