Title: Introduction to Basic Crystallography - Zones in the EBSP

1
Introduction to Basic Crystallography - Zones in
the EBSP
• In an Electron Backscatter Diffraction Pattern
(EBSP), the intersection of Kikuchi bands
correspond to 'Zones Axes' in the crystal

These can be 'indexed' and displayed
2
Introduction to Basic Crystallography - Indexing
• Indexing an (EBSP) refers to the recognition and
labelling of bands and zones in the pattern,
which relate to specific planes and directions in
the crystal.

3
Introduction to Basic Crystallography - Euler
Angles
• Euler Angles are the three rotations about the
main crystal axes
• Euler angles are one possible means of describing
a crystal orientation

4
Introduction to Basic Crystallography - Euler
Space
• Euler Space was popularized for macro-texture
investigations as the 'Orientation Distribution
Function' (ODF).
• ODFs are an established method for interpreting
the results from x-ray diffraction

5
Introduction to Basic Crystallography - The
Orientation Matrix
• The orientation matrix describes the absolute
orientation of the crystal with respect to the
sample axes.

6
Introduction to Basic Crystallography - Ideal
Orientation Nomenclature
• In this example the orientation of the crystal
shown can be written as 100lt110gt

7
Introduction to Basic Crystallography -
Misorientation
• Misorientation is the expression of the
orientation of one crystal with respect to
another crystal.
