Applications in research and production
Understanding texture is essential. For example, texture is a critical parameter in the production of metals, like steel and aluminum in order to control properties such as mechanical strength (e.g. in tool inserts) and formability. In mineralogical and geological sciences, deformation history of the Earth is investigated by measuring the texture of rocks. Analyzing orientation distribution can help to understand the formation process of the artifacts. By tuning the growth conditions of thin films the desired properties can be optimized, for instance for hard disk drive materials or superconducting wires.
X-ray diffraction technique
A peak in a diffractogram represents the intensity of a certain (hkl) reflection in a certain orientation. By tilting and rotating the sample, mounted onto a diffractometer, the intensity distribution of a reflection over the orientation sphere - a pole figure - can be recorded. When a set of pole figures for independent crystal orientations has been measured, the orientation distribution function (ODF) of the crystallites can be calculated.
Discover preferred orientations
PANalytical provides a range of solutions for X-ray texture measurements. The Empyrean system equipped with a Eulerian cradle as well as the X’Pert³ MRD (XL) are ideal X-ray diffraction systems for the materials scientist who wants to measure pole figures on samples of various shapes and sizes. Subsequent analysis of the measurements for evaluation, visualization and calculations of the orientation distribution function is performed with the help of the Texture software package.
