Journal of Applied Crystallography AXES1.9: new tools for estimation of crystallite size and shape by Williamson±Hall analysis Ma È ndar, Felsche, Mikli and Vajakas Synopsis:Complicated analyses of X-ray powder diffraction peak shape on the bases of peak ®tting, the Voigt method and the Williamson± Hall plot are implemented in the form of user-friendly dialogues into an MS-DOS program. The tools are used for the estimation of apparent (X-ray) crystallite size and lattice strain, as well as the calculation of actual dimensions of crystallites, assuming spherical or cylindrical shape.

Authors wishing their names to be alphabetized differently should indicate this below. AbstractDialogues for the estimation of crystallite size, shape and lattice strain are designed and included in an X-ray powder diffraction (XRPD) program, named AXES. They implement peak ®tting and Voigt analysis followed by a Williamson±Hall plot (WHP). Eight different peak-shape functions can be used for individual peak ®tting. Volume-weighted crystallite size and effective lattice deformation are calculated from linear interpolation of the WHP. Actual dimensions (diameters of spheres, diameters and heights of cylinders) are calculated, assuming spherical or cylindrical shapes of the crystallites. Results of size±shape analyses can be visualized in the form of a WHP and as an arrow diagram (HPGL format), which shows distribution of observed apparent and true sizes of crystallites with a diffraction vector. The program has been written in Borland Pascal 7.0 for MS-DOS. The executable code is available via the World Wide Web.
