Identification and quantification of microtextured regions in materials with ordered crystal structure

A method of analyzing microtextured regions in materials with ordered crystal structure, comprising:

• obtaining crystallographic orientation information from a sample of a material under evaluation;
• performing texture processing of the collected orientation information by generating hybrid descriptors, each hybrid descriptor comprising texture information and non-texture information extracted from associated orientation information:
• wherein performing texture processing of the collected orientation information comprises:
• computing the Generalized Spherical Harmonic expansion on the orientation information;
• further comprising:
• clustering C-coefficients from the Generalized Spherical Harmonic expansion to define a new mapping;
• plotting clustered data in real space;
• plotting chord-length distributions along sample directions of interest;
• using the chord-length distributions to measure information about the dimensions of clusters in the C-Maps;
• and
• using 2-point correlations to analyze the mapping and find the probability of a vector head and tail to fall on the same feature;
• clustering the hybrid descriptors to produce orientation clusters where each orientation cluster corresponds to a dominant zone of microtexture;
• generating composite data by spatially resolving the orientation clusters to real space;
• and
• performing a local s atial filtering of the com osite data such that continuous regions of similar zones of microtexture are identified in the filtered composite data.
