OrientXplot reads information about the orientation of sets of single crystals as either orientation matrices
or as Euler angles. It therefore handles data from all commercial single-crystal diffractometers and from a variety of EBSD programs. The
program can plot the orientations of the individual crystals with respect to the instrument or, more importantly, calculate and display the
relative orientations of two crystals, for example inclusions in hosts, twinned crystals and crystals on substrates.
For a comparison between the orientations of guest crystals in different hosts, it is necessary to take into account the ambiguity
in indexing the diffraction patterns that arises from the symmetry of both the guest and the host crystals. Failure to allow for this
ambiguity can lead to errors in interpretation of orientation data, or failure to recognise systematics in the relative orientations of two phases.
In principle, the symmetry could be allowed for in the diffractometer software by re-indexing of the diffraction patterns in each of the
symmetrically-equivalent orientations, but such an approach would be time-consuming and tedious. Instead, the ‘re-indexing’ can be performed by
OrientXplot under user control and it can then display the resulting orientation data in stereograms as shown above.
Last Update: Version 7.3 (March 2017). This contains fixes for a few minor bugs found in versions 7.1 and 7.2. This new version also
allows you to save the stereographic plots to high-resolution jpegs. If you are using an older version, please update to this version.
- Before installing, uninstall previous versions of OrientXplot, by using the Uninstall utility in the Windows control panel
- For Windows, Download a self-installer and run it.
- This will install the program, example files and a pdf manual.
- After installing the program, read the manual for more information!
- The manual and published paper describing the program will be in the same folder as the program.
- The example files will be in your directory \Documents\OrientXplot
