SUMMARY Thin foils of pure molybdenum single crystals with selected surface orientations and tensile axes were tested on a double‐tilt straining stage using a microscope operating at 800 keV. Studies were made of the propagation of screw and edge dislocations, slip geometry, dislocation multiplication and formation of dislocation tangles. Special attention was paid to the influence of the surface on dislocation motion and the comparison of observed effects with those of bulk material.
