The fine structure of slip-lines that was produced during the first stages of compressive deformation of single crystals at 300 to 900K was examined by means of scanning force microscopy. An evaluation scheme was developed in order to describe the distribution of local shear with regard to the clustering of slip. This permitted conclusions to be drawn concerning the distribution and activity of dislocation sources, as well as the transition of slip to neighboring planes via cross-slip.
