Furthermore, we also apply ghost correction and compare the approximation error to the previous reconstructions. LCC Cell Processing of X-Ray crystallographic data.

The program originally written for a main-frame computer was adapted for a PC by R.Gladyshevskii. LAZY PULVERIX Simulation of x-ray and neutron powder diffraction patterns. As the second step, the ODF can be estimated from these pole figures by using one of. LAYER Reciprocal lattice plotting programs for diffractometer data. calcError ( odf, model_odf, 'resolution', 5 * degree ) ans =Ġ.0815 Exploration of the relationship between estimation error and number of pole figuresįor a more systematic analysis of the estimation error, we vary the number of pole figures used for ODF estimation from 1 to 7 and calculate for any number of pole figures the approximation error. One family of methods relies on single crystal diffraction, namely. Which can be plotted, plot ( odf, 'sections', 6, 'silent', 'sigma' )Īnd compared to the original model ODF. Kernel: de la Vallee Poussin, halfwidth 5°Ĭenter: 29758 orientations, resolution: 5° plot ( pf ) ODF Estimation from Pole Figure Dataįrom these simulated pole figures we can now estimate an ODF, odf = calcODF ( pf ) odf = ODF Here we assume that the mean intensity is 1000. pf = calcPoleFigure ( model_odf, h, r ) pf = PoleFigureĪdd some noise to the data. Now the pole figures can be simulated using the command calcPoleFigure. WBV orientations on a colour coded map or plotting in inverse pole figures. The grid of specimen directions r = regularS2Grid ( 'resolution', 5 * degree ) Schematic illustration showing (left) how dislocations of the same sign will.

Finally, we include a simple software tool, written in both MATLAB® and Python, which the reader can use to compare consistency with their own microscope set-up and which may act as a springboard for further offline analysis. These case studies can be generated easily in most laboratories and represent an opportunity to demonstrate confidence in use of recorded orientation data. 6 (a), many linear parts propagated in a mutually parallel manner inside the Si grain, and the lithiation displayed anisotropy, as in Fig.

This is supported through a series of case studies examining particular features of the microscope settings and/or unambiguous crystallographic features. Figure 6 shows an SEM image, inverse pole figure (IPF) map, and schematic diagram of Li intrusion in a Si grain based on the Si crystal lattice. A fundamental outcome of this analysis is to note that the beamshift coordinate system needs to be precisely defined for consistent 3D microstructure analysis. We establish a coordinate system rooted in measurement of the diffraction pattern and subsequently link this to all other coordinate systems. These conventions have been used to successfully demonstrate that a consistent frame of reference is used in the sample, unit cell, pole figure and diffraction pattern frames of reference. In this paper we outline a series of conventions used to describe crystal orientations and coordinate systems. Unfortunately, due to crystal symmetry and differences in the set-up of microscope and EBSD software, there may be accuracy issues when linking the crystal orientation to a particular microstructural feature. There are many sophisticated software packages that present measured data. Electron backscatter diffraction (EBSD) is an automated technique that can measure the orientation of crystals in a sample very rapidly.
