Abstract Scope |
We present and discuss a variety of chemo-structural phenomena caused by the interplay between an alloy’s chemical composition and its lattice defects. Observations are documented by using correlative atom probe tomography, electron microscopy and theory.
The features discussed include such diverse phenomena as solute chemical decoration, partitioning and phase transformations at dislocations; dislocation-character-specific chemical decoration; and low-dimensional spinodal decomposition within interfaces. It is shown that some of these phenomena have a structural and kinetic background while others are thermodynamic in origin and can be explained by stable low-dimensional phase states at defects. |
