The anisotropy of strain distortions in nanocrystalline vanadium carbide VC0.875 powders has been experimentally studied using Xray diffraction. It has been shown that the inclusion of microstrain anisotropy and inhomogeneous broadening in the analysis make it possible to more accurately describe experimental data on diffraction reflection broadening. It has been found that strain distortions mainly contribute to the broadening of diffraction reflections of VC0.875 nanopowders produced by highenergy ball milling.
