DIFFRAC.TEXTURE

Materials and components properties are significantly influenced by an inherent or applied preferred orientation, or texture, which can be non-destructively investigated by X-ray diffraction methods.

DIFFRAC.TEXTURE is the powerful and easy-to-use software suite designed to analyze texture measurements. By utilizing a systematic approach to analysis according to a flowchart, DIFFRAC.TEXTURE delivers comprehensive texture information with just a few mouse-clicks.

DIFFRAC.TEXTURE features two well established and complementary techniques to provide the most accurate and reliable results: the model independent Spherical Harmonics methods and the model dependent Component Method.
With the implementation of the latter in DIFFRAC.TEXTURE, all crystal systems are now supported and the variety of sample symmetries ensures that a huge diversity of textures can be handled.

• Straightforward creation of pole figures from 0D, 1D and 2D measurement data with single-click assignment to crystal phases.
• Component method for fully detailed model based texture analysis.
• Spherical Harmonics method for direct computation of the Orientation Distribution Function.
• Powerful texture representation capabilities and extensive report generator.

The generation of pole figures from measured data has never been easier. DIFFRAC.TEXTURE can import data measured with 0D, 1D or 2D detectors and instantly create pole figures with single click operation either from selected angular regions (1D) or directly from 2D frame stacks via a single frame-cursor selection.

DIFFRAC.TEXTURE comes with a comprehensive crystal structure database that allows linking of pole figures to the corresponding hkl reflections with the least effort. Overlapping signals from different phases can be easily assigned to facilitate data analysis.

DIFFRAC.TEXTURE includes powerful tools and options for a more detailed analysis of the obtained textures:

• ODFs can be computed and represented in 3D or as a set of 2D sections.
• Inverse pole figures along the surface normal, in-plane rolling and transverse directions.
• 3D visualization of the individual texture components to support a better understanding of their orientation.
• Pie-chart representation of the components’ volume fractions, including the isotropic content.

The Spherical Harmonics method is a model-free approach and the method of choice if the orientation distribution function is of primary interest.

The ODF is directly calculated from a series expansion of the measured pole figures using a set of special functions defined on the surface of a sphere – the generalized spherical harmonics.

The advantage of the method is that it provides texture results in form of the ODF in a fast and simple way without requiring much prior sample knowledge.
