Abstract
A detailed theoretical analysis has been made of the stress fields which arise from the motion of glide dislocations across a symmetric tilt boundary. These stress fields are long range and result from the formation within the boundary of virtual grain boundary dislocations. A similar type of long range stress field is generated when two crystals of differing lattice size are joined together. In the former case the long range stress fields may be sufficient to generate dislocation glide loops while in the latter case these loops are of the prismatic type and move by climb. Portions of both types of loops move to the boundary and become incorporated into them as interface dislocations, in turn reducing the long range stress fields arising from the virtual dislocations.
