Abstract: EBSD measurements were performed on as-received and on cold deformed DP600 plate material in order to characterize the substructure development with mechanical straining. Even in the undeformed material, a slight lattice curvature in the ferrite was observed at the phase boundaries with martensitic grains, while such a curvature was not observed at ferrite–ferrite grain boundaries. Upon mechanical straining, a strong curvature develops predominantly around martensitic grains. At high strains this results in orientation differences of up to 35◦ within ferritic grains. In contrast to the substructure development in IF steel, no pronounced dislocation walls exist in this DP steel, even after 50% cold rolling reduction.
