Three different methods are used for the quantitative local texture analysis of fibre textures. Two methods are based upon the evaluation of BRAC-BRENTANO diffraction diagrams. In the first method relative intensity parameters are calculated, whereas in the second Rietveld preferred orientation factors are determined. The third method uses measured pole figures and the series expansion (Bunge).

The method is applied to hot backward extruded NdFeB ring magnets. A local texture determination dependent on a sample surface distance is possible. The results are compared with magnetic measurements.
