Dislocations in Layer Structures

Abstract

Amelinckx and Delavignette1 have recently studied non-metallic substances with layer structures, including talc and graphite, by transmission electron microscopy. They observed nets of widely dissociated dislocations particularly in talc. Splitting into more than two partial dislocations in such hexagonal layer substances had been forecast by Kronberg2. Grenall3 has observed dislocations in graphite previously, but did not observe dissociation into partials.
