This paper shows a complete study about the characterization of the texture and the microstructure evolution of an industrial thermo-mechanical processing aiming to develop an advanced soft magnetic Fee27%Co material with a sharp Goss texture. Thanks to its intrinsic magnetic properties, such an alloy should be able to get a place in the market of aircraft transportation transformers. It appears that the development of a highly Goss textured Fee27%Co alloy could be achieved by optimizing the intensity of the Goss and rotated Cube texture during hot rolling using an adequate thermo-mechanical processing, namely finishing hot rolling in the ferritic phase.
