Presentation Transcript

  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: {100}<110>

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