X - ray diffraction line profile analysis of iron ball milled powders

Résumé

Abstract The size of coherently diffracting domains and the lattice strain of iron ball milled powders have been determined according to various models. The Williamson–Hall plot, the Voigt model and the Warren–Averbach model have been employed. The analytical expressions of the size and strain Fourier coefficients have been extracted from the integral breadth using the so-called “double Voigt” method. The shock power generated in the planetary ball milling equipment employed has been calculated for each synthesis condition and used to plot the size and the strain. The nature (screw or edge) and the density of the dislocations have been determined for each powder under investigation.
