Partially Pinned Boundaries in White Tin Crystals

Katuhiko Honda

(Received August 10, 1988; accepted for publication October 22, 1988)

The behavior of a dislocation boundary under various applied stresses has been studied by use of the etch hillock technique. The boundary consisted of an array of edge dislocations (the [100](010) slip system) separated with immobile dislocations (the ½<111>{110}). Since the motion of edge dislocations was obstructed by immobile dislocations, the boundary as a whole behaved as if it were partially pinned along its length. The boundary bowed between immobile dislocations under a small stress and was released at a certain critical stress. The critical stresses were within a range of about 3 to 20 gw/mm² for all observed boundaries. Based on a dislocation model already presented, the behaviors of observed boundaries were analyzed by anisotropic elasticity theory and the results were compared with observations.
