The texture of the Ni monostanogermanide phase was studied by in situ X-ray diffraction, in-plane reciprocal space mapping and pole figure analysis. Sn addition modified the out-of-plane and in-plane orientations and reduced the number of texture components.

A sharp inequality is proved between the L^{2}-norm and the entropy of probability density functions; this inequality is applied to texture analysis by characterizing the relationship between the entropy and the texture index of an orientation density function. The relationship is empirically verified with simulated and experimental data.

A simple symmetric 2D scan using a point focus beam was used to determine the fibre axis of fibre-textured satin spar samples. A geometric explanation of the `wing' feature formed by the diffraction spots in 2D scans helps to visualize the nature of the reciprocal layers of the fibre-textured samples through wide-range reciprocal space mapping.

The texture measurement capabilities of the NOMAD beamline at the Spallation Neutron Source and the NRSF2 beamline at the High Flux Isotope Reactor at Oak Ridge National Laboratory are discussed. Texture analyses using two common analysis methods, Rietveld texture analysis using the MAUD program and pole figure inversion using the MTEX MATLAB toolbox, are presented.

This paper describes the multiaxial texture of zirconia sinters used as metering nozzles and describes the correct method of phase composition determination using X-ray diffraction. Owing to phase composition changes during sample preparation, testing should be carried out on solid samples and the results corrected.
