Effect of Dislocations on X-Ray Diffraction Properties of Copper

Abstract
The effect of dislocations on both integrated intensities and rocking-curve half-widths has been studied in an (n, −n) double-crystal spectrometer arrangement on copper crystals of 103<N<108 dislocations per cm2. The results show that the rocking curve provides a suitable means of characterization of the density and the type of dislocations in this range. The changes in half-width of the rocking curve and the integrated intensity produced by the dislocations can be described satisfactorily by the model of independently scattering perfect crystal blocks up to a dislocation density of 2×105/cm2, and at higher dislocation densities, lattice tilts produced by the dislocations appear to be the main source of line broadening.
