Imaging of Atomic Structures of Metals and Alloys by High Resolution Transmission Electron Microscopy
High resolution transmission electron microscopy investigations have been carried out to study the atomic structures in metals and alloys. Three topics are presented: firstly, solid to solid martensitic phase transformations in Co alloys; secondly, the early stages of precipitation as well as electron radiation induced defects in Al alloys, and thirdly, dislocation structures in plastically deformed long range ordered intermetallic alloys. In all three cases the aim was to find a correlation between macroscopic properties and their underlying atomic structures.
