Effect of Hot and Cold Rolling on Grain Size and Texture in Fe-2.4wt%Si Strips

The magnetic properties of electrical steel such as magnetization behavior and specific magnetic losses are related to the microstructure and texture of the steel. The interest in the case of FeSi-alloys is to realize a low intensity on the $\{111\}$ fiber, which is a different goal than that of conventional steels, where a high intensity on the $\{111\}$ fiber and small grain size is desired. In this paper, we present and discuss some results of our recent studies on FeSi-alloys without phase transformation. The resulting grain structure and the relevant magnetic texture components for nonoriented electrical steels before and after cold rolling as well as after annealing were analyzed.
