Abstract

The momentum method for the evaluation of size and strain parameters from X-ray peaks is applied to the case of a ball-milled iron powder. The Warren-Averbach analysis and the anisotropy of the peak widths revealed by the Williamson-Hall plot indicate that broadening is caused by lattice strain and anisotropic crystallite size. The separation of the two components was performed based on the momentum method developed for the case of size and dislocation induced strain broadening. The evaluations show that the crystallite sizes in the 211 and 100 directions are smaller than in the 110 direction. The coherent domains are rather small ranging from 5 to 10 nm and contain of about one dislocation. No indication for the presence of stacking faults was found.
