Texture research of metals and rocks on the KSN-2 neutron diffractometer

摘要

From the industrial point of view the research activities of the Laboratory of Neu-tron Diffraction (Faculty of Nuclear Sciences and Physical Engineering CTU Prague) areconcentrated to the quantitative texture analysis based on the ODF (orientation distributionfunction). We have developed the experimental and data treatment procedures for this typeresearch. The texture experiments were carried out on the neutron diffractometer KSN-2using the TG-1 texture goniometer. This diffraction device offers good intensity with wave-lengths in the range 0.095 to 0.141 nm. Experimental data in form of the pole figures or theinversion pole figures were treated by means of these codes: popLA, TODF-N, MAUD,GSAS. Quantitative texture analysis by means neutron diffraction data were used on theinvestigation of the many samples of the technically interesting materials. For example, wehave determined the texture parameters on the oriented Si steel sheets and rock materials(limestone test samples).
