Step-by-step instructions on the flow bar allow smooth calculation of the crystal orientation distribution map

• Pole figure representation and Orientation Distribution Function (ODF) analysis
• Representation and analysis on complete pole figures obtained from transmission and reflection measurements
• Analysis of preferred orientation direction (hkl)[uvw] and its volume fraction
• Inverse pole figure calculation
• Kearns and Herman’s orientation functions for quantitative analysis

Creating and displaying pole figures

Texture plugin is designed to analyze the ODF (Orientation Distribution Function) from pole figure data measured with 0D or 2D detectors. The plugin supports defocusing correction and absorption correction of pole figures. In addition, the plugin includes functions such as smoothing, rotation and regrid of the pole figures. Measured 2D data, 2D diffraction data polarization correction and absorption correction are also available. Pole figures can be displayed in different formats.

ODF calculation (optional) Two methods of ODF calculation are available: WIMV and the component approximation analysis method. Both methods are suitable for the calculation of a crystal orientation distribution map and recalculation of whole pole figure corresponding to an arbitrary index. One of the optimization algorithms for component approximation is the genetic algorithm. When using this algorithm, there is no need to match parameters with a measured pole figure beforehand.

Also, the inverse pole figure can be created using the obtained crystal orientation distribution map.

Calculation of orientation function

An orientation function can be calculated by connecting transmission and reflection pole figures, or overall pole figures recalculated by ODF analysis. “Information” contained in the pole figure can be compared and managed as “values” presenting a degree of orientation. Differences in physical properties and performance due to differences in production methods can be evaluated through the connection to an orientation function obtained from the pole figures.
