Secondary grain-boundary dislocations in (001) twist boundaries in MgO. II. Extrinsic structures

PDF Version Also Available for Download.

Description

Extrinsic secondary grain boundary dislocation (GBD) structures were observed by weak beam transmission electron microscopy in a variety of (001) twist boundaries in MgO. These structures were derived from segments of lattice dislocations embedded in the boundaries and could be interpreted as the result of the decomposition of the lattice dislocations into extrinsic GBDs and the subsequent interaction of the product GBDs with the intrinsic boundary structure. The results demonstrate that lattice dislocations in MgO are attracted to grain boundaries over a wide range of conditions and tend to remain embedded in the boundaries as extrinsic GBD structures.
