MODULE 5 - Data Presentation for EBSD
• Reference Axes
• Pole Figures
• Inverse Pole Figures

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:

• each orientation is displayed as a single point
• Many measurements show alignment trends
