Electron backscatter diffraction (EBSD) is a technique that can determine the local crystal structure and crystal orientation at the surface of a specimen. The methodology collects elastically back scattered electrons (BSEs) which have undergone coherent Bragg scattering as they leave the specimen. A dedicated EBSD detector collects the scattered BSEs over a large solid angle, which forms electron backscatter diffraction patterns made up of Kikuchi bands.
The EBSD patterns can be analyzed to give the crystalline structure and orientation of the crystal. EBSD analysis in SEM is now very automated and has found widespread application in the analysis of crystallography of metallic alloys.
A dedicated user-friendly software has been developed for segmentation and analysis of EBSD images used for microstructural analysis of materials. The software has been developed using Python language and PyQt GUI development tools. The menu driven GUI enable the user to carry out selection of EBSD data, segmentation of images and generation of various MAPS like the PF and IPF.
An EBSD library has been created with functions/methods to carry out various image operations such as KAM, KAM based segmentation, IPF and PF which can be installed and accessed in any Python development environments like the Spyder.
The developed software has been used to carry out these operations on different specimens exhibiting different crystal characteristics and has been compared with a commercially available package. The performance has been found to be satisfactory. The scientific community will be richly benefited by this analysis software, which is efficient, benchmarked, and cost-effective.
