Abstract
In order to investigate the texture formation of Nd-Fe-B system sintered magnet, 006 Miller indices pole figures of (Nd⋅Dy)2Fe14B phase were measured for as-compacted sample and for as-sintered one by X-ray diffraction. The degree of preferred orientation P was estimated by the integration of the product between the normalized diffraction intensity IN and cosα, which α is the inclined angle between the direction of the applied magnetic field and that of the magnetic moment in each grain. As a result, P had good corelation with the remanence Br in sintered sample. P in as-compacted sample was always lower than that in as-sintered one. The difference between as-sintered state and as-compacted state was largest when the magnetic field was 0.2T.
