摘要

The measurement of the final Goss texture sharpness in grain-oriented electrical steels is a challenging task due to the immense grain size ranging from millimeters to centimeters. Although it is widely claimed in the literature that the orientation deviations from the ideal Goss orientation lie in the range of about seven degrees for conventional grain-oriented steel and about three degrees for high permeability grades, no precise investigation with an appropriate statistical relevance is known to the authors.In this work, X-ray diffraction (XRD) and large-area electron backscatter diffraction (EBSD) based orientation microscopy were used for texture analysis and orientation determination in order to estimate the Goss orientation spread of different grades of grain-oriented steel. Additionally, two production routes for grain-oriented steel sheets are compared, the conventional route and a low heating route with lower inhibitor strength. The results of the texture measurement demonstrate that both routes deliver comparable values of orientation deviations. Furthermore, it can be shown that small differences in magnetic properties can be correlated with the texture sharpness of the material.
