Study of Microstructure and Texture Evolution in Grain-Oriented Steels Via Coercivity Measurements

The relationship between microstructure, phase transformation, and texture in grain-oriented (GO) steels on the one side and the magnetization processes on the other side is very complex. To contribute to a better understanding of this dependence, the magnetic measurements were carried out on the steels in combination with a microstructure, texture, and phase analysis. It was shown that the coercivity measurement technique can be successfully applied to reflecting of main microstructure and texture changes of GO steels. The mentioned changes taking place during application of particular thermomechanical treatments. Moreover, this measurement method also can be applied to detect phase transformations in the materials containing sufficient carbon content. Within this paper, it is shown that the measurement of coercivity is a powerful tool that can be successfully used to reflect such important phenomena as microstructure and texture development in the GO steels.
