Data Presentation for EBSD - Reference Axes

• Reference axes are required

• The specimen axes are convenient for this purpose

Data Presentation for EBSD - Pole Figure

• Shows the orientation graphically

• Shows whether preferred orientation is present when many measurements are plotted

Data Presentation for EBSD - Pole Figure

• A highly populated Pole Figure (one with many different measurements plotted) is useful for evaluating the orientation distribution

Data Presentation for EBSD - Inverse Pole Figure

• The axes are crystallographic directions, not sample directions as in a pole figure

• This conveniently shows the orientation of planes to a chosen surface

Similar to a Pole Figure, but:

Data Presentation for EBSD - Inverse Pole Figure

• each orientation is displayed as a single point

• Many measurements show alignment trends
