Quantification of the effect of texture on the magnetization behavior

Jürgen Schneider – Armin Franke – Anett Stöcker – Rudolf Kawalla

   For electrical steels there is a need to describe the intensity of the present texture components in the finally processed material as well as after the various processing steps. Preferable texture components like the cube fibre texture will improve the magnetization behaviour. Furthermore, there is interplay between the various processing steps at fabrication on the resulting final texture in the fully processed material. A texture parameter A can be derived from the orientation distribution function (ODF) for arbitrary texture, which describes the texture for each texture components. Taking into account this fact, we used a so-called A-map. The A-map gives the value of A for each point in the Euler space for fixed constant values of 2 or 1. This A-map may be used to estimate immediately the effect of a different resulting image of texture due to variation of the technology of fabrication of the material. Any increase of the intensity of texture within the area of the ODF, where the A-values are smaller than a certain value, results in improved magnetization behaviour. Within the paper some examples are given.
