Abstract
ABSTRACTExperimental observation of many interfaces in metals indicate the presence of a dislocation-like structure. The geometrical basis for such a structure to exist is discussed, and the suitability of the transmission electron microscope (TEM) to characterise it considered. It is shown by reference to examples of grain and phase boundary structures in metals that such geometrical models may be used as a first step to predicting interfacial structures, and that the dislocations observed may play a role in thermo-mechanical behaviour of polycrystals. The general applicability of the applicability of the approach to non-metallic systems, such as semiconductors and ceramics is also indicated.
