Abstract

The magnetic properties of electrical steels are related to the microstructure and texture of the final processed steel. There is an interplay and interaction of the microstructure and texture between the various processing steps. The ongoing structural changes at final annealing of the cold rolled material depend sensitively on the deformation structure after the cold rolling with high deformation. In this paper, we will study in detail the role of the microstructure of the hot strip on the deformation structure after cold rolling with high deformation.
