dc.description.keywords An important step in quantifying dislocation broadening of a line profile is the evaluation of the dislocation contrast factors. In this wau the elastic properties of the material, displacement field of the dislocations and geometric orientation of the diffraction vector relative to the dislocation slip-system are incorporated into the analysis. We present a detailed description of how to carry out a first-principle evaluation of the contrast factors for a range of industrially important materials. This requires an understanding of the displacement fields and slip systems of dislocations in elastically anisotropic materials. This approach enables the contrast factors and Fourier coefficients for single crystal, textured and poly crystalline specimens to be determined. In this discussion we also present detailed exampes of the evaluation of the contrast factors for a range of face-centred and body-centred cubic materials. An atypical case is also presented which demonstrates the need of a first principles approach to determining the contrast factors. en_US
