Dynamical simulation of EBSD master pattern of aluminium

Dynamical simulation of an electron backscatter diffraction (EBSD) master pattern of aliminium (Fm\(\bar{3}\)m, a = 4.04 Å). The master pattern was simulated with EMsoft v4.1. The HDF5 file includes master patterns of the upper and lower hemispheres, in both the stereographic projection and the square Lambert projection, of accelerating voltages from 10 to 20 kV with an increment of 1 kV.

The HDF5 file can be opened with any HDF5 reader, e.g. the applications HDFView and HDFCompass or the Python library h5py. The file can also be read and plotted with the Python library kikuchipy (https://kikuchipy.org). Assuming Python and the library is installed, the stereographic projection of the master pattern with all energies can be read and plotted with the following commands:

import kikuchipy as kp
s = kp.load("/path/to/am_mc_mp_20kv.h5")
s.plot()

The PNG file shows the stereographic projection of the upper hemisphere of the master pattern from 20 kV. The al.xtal file was produced with the EMsoft program EMmkxtal, contains a complete description of the crystal structure, and is used as input to the EMsoft programs EMMCOpenCL and EMEBSDmaster. The latter two programs produced the al_mc_mp_20kv.h5 file.
