“…As already mentioned, a volume correction is needed if the effective volume changes during sample tilting and rotation . Because the irradiated gauge volumes during tilting and rotation have a complex shape, a 3D software package named Gambit 2.4.6 (product from Ansys) was used to determine the gauge volume for any pole figure points following the same steps in χ tilting (six positions) and φ rotation (72 positions).…”

The handling of larger samples for texture studies is limited when we using the Eulerian cradle. The robot Stäubli RX160 installed at STRESS‐SPEC offers much more freedom in sample manipulation on one hand to perform pole figure scanning and on the other hand to position the sample for a texture mapping. A key problem is that slit systems cannot be positioned close to large samples due to safety reasons which makes corrections more important. A very simple solution was tested to correct the scattered intensity for each pole figure point for constant volume and anisotropic absorption. A simple method to make these corrections is needed because engineering samples such as semi‐finished products have a large variety of shapes and weights and an ideal slit system is only seldomly available. The test sample was a Cu‐tube of 140 mm in diameter with an average wall thickness of 10 mm. To compare the corrections three kind of samples were measured, first a cube of 10 × 10 × 11 mm³ without any correction, second an 11 mm long tube segment and third a tube segment of 250 mm (12 kg weight) in length. Orientation Distribution Function (ODF) analysis of the average texture over the tube wall by the iterative series expansion method has shown that sufficient intensity corrections can be done to describe the texture gradient around the circumference of the Cu‐tube related to low ovality and eccentricity of the Cu‐tube.

“…For example Montesin et al. performed a correction to obtain corrected pole figures of wire. A specific case is the anisotropic absorption of two‐phased materials which is a key problem for x‐ray texture measurement of lamellar microstructures .…”

Quantitative analysis of crystallographic preferred orientation (texture) of very small volumes in ®ne-grained polycrystalline materials has been carried out with a monochromatic X-ray microbeam ( 30 mm) at the microfocus beamline of the European Synchrotron Radiation Facility (ESRF). The experimental procedure is described and illustrated with textures of rolled aluminium, aluminium and steel wires, polymer ®bers and natural bone material (apatite).

Absorption Corrections for X‐Ray Texture Measurement of Any Shape Sample

Abstract: A pole figure needs generally more than 2000 points of measurement, each point corresponding to a specific location of the sample in space. For each position, the detected intensity will depend on the irradiated volume,
