Resolving pseudosymmetry in tetragonal ZrO2 using EBSD with a modified dictionary indexing approach

2 code implementations10 Mar 2020 Edward L. Pang, Peter M. Larsen, Christopher A. Schuh

Resolving pseudosymmetry has long presented a challenge for electron backscatter diffraction (EBSD) and has been notoriously challenging in the case of tetragonal ZrO2 in particular.

Minimum-Strain Symmetrization of Bravais Lattices

1 code implementation8 Oct 2019 Peter M. Larsen, Edward L. Pang, Pablo A. Parrilo, Karsten W. Jacobsen

In computational analysis of Bravais lattices, fulfilment of symmetry conditions is usually determined by analysis of the metric tensor, using either a numerical tolerance to produce a binary (i. e. yes or no) classification, or a distance function which quantifies the deviation from an ideal lattice type.

Global optimization for accurate determination of EBSD pattern centers

1 code implementation28 Aug 2019 Edward L. Pang, Peter M. Larsen, Christopher A. Schuh

Accurate pattern center determination has long been a challenge for the electron backscatter diffraction (EBSD) community and is becoming critically accuracy-limiting for more recent advanced EBSD techniques.
