During the deformation of low carbon steel by cold-rolling, dislocations are created and stored in grains depending on local crystallographic orientation, deformation, and deformation gradient. Orientation dependent dislocation densities have been characterized by the broadening of the X-ray diffraction lines measured on two complementary synchrotron experiments. Different cold-rolling levels (from 30% to 95% thickness reduction) and material states (deformed and restored) have been considered. One experiment was dedicated to the study of some specific crystallographic orientations and the other one to get a mapping of stored energy in the Euler space. The advantage of the gamma fibre grains during the recrystallisation is quantified, with a stored energy two times higher than the alpha fibre grains. Results were confirmed by an independent analysis of EBSD data.
