The electromagnetic properties of strips made of grain-oriented electrical steels (GOES) are strongly affected by the sharpness of the Goss texture. The Goss texture is defined by {110} 001, where the planes {110} are parallel to the surface of the strip and the directions 001 are parallel to the rolling direction. The formation of this texture is the result of a complex technological process, which consists of hot rolling, two-stage cold rolling, decarburization annealing and final high-temperature annealing. To date, however, the phenomenon of preferential growth of grains with a Goss orientation during secondary recrystallization has not been fully elucidated.This work aimed to create a correlation method that will allow obtaining more data on the structure and microtexture in GOES strips. Thus, a combination of macrostructure images and electron backscattered diffraction (EBSD) analysis was studied. Cross-sections through macro samples were used for EBSD analysis. They were cut in defined areas of macro samples so that it was possible to assign EBSD results to macrostructure images and obtain simultaneous information about size and orientation of grains. The main advantage of the methodology is that using EBSD data on grain orientation, which are obtained by analysis of defined cross-sections taken from macro samples, it is possible to define very effectively the orientation of individual grains for a relatively large area of GOES strips.
