Crystallographic analysis of the lattice metric (CALM) from single electron backscatter diffraction or transmission Kikuchi diffraction patterns
(Journal of Applied Crystallography, 2021-05-28)A new software is presented for the determination of crystal lattice parameters from the positions and widths of Kikuchi bands in a diffraction pattern. Starting with a single wide‐angle Kikuchi pattern of arbitrary ... -
Use of electron backscatter diffraction patterns to determine the crystal lattice. Part 1. Where is the Bragg angle?
(Journal of Applied Crystallography, 2023-02-24)The derivation of a crystal structure and its phase‐specific parameters from a single wide‐angle backscattered Kikuchi diffraction pattern requires reliable extraction of the Bragg angles. By means of the first derivative ... -
Use of electron backscatter diffraction patterns to determine the crystal lattice. Part 2. Offset corrections
(Journal of Applied Crystallography, 2023-02-24)A band width determination using the first derivative of the band profile systematically underestimates the true Bragg angle. Corrections are proposed to compensate for the resulting offset Δa/a of the mean lattice parameters ... -
Use of electron backscatter diffraction patterns to determine the crystal lattice. Part 3. Pseudosymmetry
(Journal of Applied Crystallography, 2023-02-24)A pseudosymmetric description of the crystal lattice derived from a single wide‐angle Kikuchi pattern can have several causes. The small size (<15%) of the sector covered by an electron backscatter diffraction pattern, the ...
