Abstract

A program for 3-dimensional texture analysis using the harmonic method has been developed. Pole figure inversion as well as ODF representation of individual orientation data are provided up to a series expansion degree of 150. The number of orientations or pole figure points is not limited. All point groups for crystal and sample symmetry, including the icosahedral group for investigation of quasicrystals are supported. Pole figure inversion is carried out using the positivity method with separation of partial or total coincidences. Several autocorrelation functions e.g. the OCF (crystal and sample symmetry) and the reduced MODF as well as correlations between different data sets can be calculated and, as an additional tool, averaging of tensor properties with arbitrary rank and symmetry is enabled. The graphical representation contains Euler cuts of the orientation distribution functions, stereographic or equal area projections of pole figures and inverse pole figures as well as diagrams showing mean values and variances of the C coefficients.
