Debye–Scherrer patterns, obtained from X-ray diffraction experiments usingsynchrotron light in transmission geometry, were analysed to constructgeneralized pole figures, and further used as input for an orientation distributionfunction inversion algorithm. By using Langford’s method for separating strainand size contributions to peak broadening, it was possible, for the first time, to obtain full domain size and dislocation density generalized distributionfunctions (GDFs). This method was applied to cold-rolled and annealedinterstitial-free steel. The predictions made using GDFs were corroborated byelectron backscatter diffraction measurements and were also consistent withwhat was previously known for this kind of material under these conditions.
