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 ... -
Manual measurement of angles in backscattered and transmission Kikuchi diffraction patterns
(Journal of Applied Crystallography, 2020)A historical tool for crystallographic analysis is provided by the Hilton net, which can be used for manually surveying the crystal lattice as it is manifested by the Kikuchi bands in a gnomonic projection. For a quantitative ... -
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 ...
