| Abstract: | The in-situ high voltage electron microscopic method has been used to study the phenomenon of spontaneous screw dislocation accelerations near the wedge-like edges of molybdenum single crystal specimens. The effects of either of the free wegde surfaces on dislocation mobility have been included in the discussion of this phenomenon. The experimental data were used to evaluate the surface image forces. |
