Abstract
The dynamical theory of diffraction contrast is applied to elastic inclusions. The visibility of such inclusions is discussed, and the best conditions for obtaining information about the state of strain around them derived. It is shown how strains can be measured around prismatic dislocation loops, and G.P. 2-type precipitates. An Appendix shows how it may be possible to derive information about the type of strain field surrounding a precipitate by a study of its image.Keywords
