Nanobeam electron diffraction strain mapping has been used to measure the strain evolution in stainless steel under in situ deformation. As the amount of deformation increases, the leading dislocation of a planar slip band leaves behind a residual strain in the form of a small lattice expansion. Dislocation analysis confirmed that the dislocations involved were <011> type. Even though, the characteristic residual strain of planar slip has often been observed, it has never before been directly measured. Our conclusions provide a view into the dynamic mechanisms of planar slip, and showcase the possibilities of multidimensional in situ imaging.
