As a preparation for the study of dispersed particles in the aluminium alloys the ALCHEMI method was tested on a simple model material. This method combines the X-ray spectrum analysis and the dynamic diffraction to provide the information on site occupancies. The site preference of Cr in the Fe3Al and FeAl materials was studied. Measured variation of the X-ray yields with the orientation near the Bragg position was fitted by the calculated curves. We found that 70 resp. 80 % of Cr occupy the Al sublattice.
