Abstract
The size of the regions of coherent scattering and microstrain are determined using «double-Voigt» method and XRD data (integral breadth of 8 diffraction) for titanium carbide nanopowders obtained by plasmachemical synthesis. The results are compared with similar characteristics calculated by Williamson – Hall method. The coherently scattering domain size ranges within 12 – 180 nm. The size of coherent scattering domain determined by x-ray diffraction method for titanium carbide powder is close to the particle size calculated by the BET method. The Double Voigt method is advantageous for boundary (both for small and large) values of the size of titanium carbide particles. The broadening of x-ray diffraction peaks is attributed mainly to the small size of coherently scattering domains. The rms microstrain values are negligible (0.0001 – 0.0004).
