    Matching

## Description

- description: The effects of the lattice parameter of the simulated master pattern
    and the EBSD pattern resolution for indexing of EBSD patterns via pattern matching
    (Spherical Indexing) were investigated using annealed austenitic steel. A larger
    deviation from the accurate lattice parameter in the master pattern resulted in
    a larger deviation from the true crystallographic orientation. Poorer EBSD pattern
    resolution resulted in a lower angular resolution, especially near the grain boundary,
    and increased kernel average misorientation (KAM) values. These results suggest
    that accurate lattice parameter and higher pattern resolution are required for
    Spherical Indexing to achieve a better angular resolution. Nevertheless, Spherical
    Indexing using a master pattern with a 15 % deviation from the accurate lattice
    parameter and EBSD patterns with a binning of 8x8 provided a better angular resolution
    than traditional indexing using the Hough transformation of EBSD patterns without
    binning (binning of 1x1). This indicates that Spherical Indexing is an excellent
    indexing procedure in terms of angular resolution, which is robust for the lattice
    parameter of the master pattern and EBSD pattern resolution.
