Hi, One should be careful with interpretation of anisotropic line broadening. Anisotropic line broadening can be due to the formation of small dislocation loops, dipoles or some early stages of pre-precipitation (GP zones) in the alloy. Would be nice if you can obtain information about diffraction intensity in rocking direction. Thus you can verify the parameters of dislocation structure you obtained. See, for example, R.I.Barabash, P.Klimanek, "Phenomenological and microscopical description of scattering by different dislocation arrangements", Zeitschrift fur Metallkunde, 1, 70-75, (2001)
