How do I do it?

The practical pages, ordered along a typical analysis from import to figures.

Import, export and reference frames

Load EBSD, pole figure, orientation and tensor data, set the reference frames, and write results back out.

19 pages

Preparing EBSD maps

Select phases and regions, fill and denoise maps, regrid, and handle pseudo-symmetry.

8 pages

Correlating maps and images

Align EBSD maps with SEM images and other maps, and correct distortions.

3 pages · 3 case studies

Orientation maps

Colour maps by orientation or property, choose colour keys, and plot orientation populations.

5 pages

Grains

Reconstruct grains, select and merge them, and work with their neighbours.

7 pages

Grain size and shape

Area, perimeter, fitted ellipses, convex hulls and projections of grains.

4 pages · 1 case study

Orientation spread and dislocations

KAM, GROD, GOS, orientation profiles, GND density and weighted Burgers vectors.

7 pages · 1 case study

Grain boundaries

Select, plot and classify boundaries: CSL, twins, subgrains, curvature, triple points.

15 pages

Texture from EBSD

Estimate ODFs and direction densities from individual orientations.

4 pages

Texture from pole figures

Correct X-ray and neutron pole figures and reconstruct the ODF.

7 pages · 7 case studies

Describing and plotting textures

Model textures, plot them in pole figures and sections, and measure components and strength.

8 pages

Physical properties

Tensor arithmetic and averages, wave velocities, piezoelectricity, optics, magnetism.

7 pages · 3 case studies

Plasticity and texture evolution

Taylor and Sachs models, slip transmission, twinning and texture evolution.

6 pages · 3 case studies

Parent grains and phase transformations

Fit orientation relationships, reconstruct parent grains and predict transformation textures.

9 pages · 2 case studies

3D data

Volume EBSD, three-dimensional grains, their boundaries, size and sections.

7 pages

Figures

Plot types, projections, alignment, colour ranges, annotations and export.
