Abstract:The most important advantages of the application of the neutronographic diffraction in texture investigations as compared to the X-ray interference method are described. Comments on the experimental technology used with Rossendorf's reactor and the applied methodology of investigation for the fully automatical measurement of complete pole figures follow. Some of the recent results of texture research at fcc and bcc metals and alloys are discussed on the base of the three-dimensional orientation distribution functions. – Investigations into the texture development in cold-rolled copper reveal that the preferred orientations are represented by a characteristic tube that is shortened at the transition to α-brass with concentration of zink increasing and the rolling degree raising respectively. – As the measurements at iron demonstrate the ideal orientations used for the specification of the rolling-texture development in bcc metals correspond to those of the texture of copper if the indexes of rolling and normal direction are interchanged. – According to the Taylor theory, textures appear at the surfaces of aluminium wires that are similar to a rolling texture whereas in the wire interior ordinary fibre textures are present.
