3D atomic investigation of solute segregation to both planar and line defects in metallic alloys

D. Blavette

Résumé

The tomographic atom-probe (TAP) is an extension in the three dimensions of space of the conventional 1D atom probe. While the conventional instrument only provides one dimensional information in the form of a set of depth concentration profiles, atomic tomography makes it possible to image and analyze a small volume of material on a subnanometric scale in the three dimensions of real space. Various salient illustrations of atomic tomography potential dealing with solute segregation to linear or planar defects on boron doped materials is presented and discussed. The TAP is shown to be able to map out the distribution of chemical species along grain boundaries in nickel base superalloys.
