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
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.
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
Introduction to Basic Crystallography - Euler
Space
• Euler Space was popularized for macrotexture investigations as the 'Orientation
Distribution Function' (ODF).
• ODFs are an established method for
interpreting the results from x-ray diffraction
Introduction to Basic Crystallography - The
Orientation Matrix
• The orientation
matrix describes
the absolute
orientation of the
crystal with respect
to the sample axes.
Introduction to Basic Crystallography - Ideal
Orientation Nomenclature
• In this example
the orientation of
the crystal
shown can be
written as:
{100}<110>
Introduction to Basic Crystallography Misorientation
• Misorientation is
the expression of
the orientation of
one crystal with
respect to another
crystal.
