Towards Corrected and Completed Atomic Site Occupancy Analysis of Superalloys Using Atom Probe Tomography Techniques

Abstract

Advanced Atom Probe Tomography (APT) techniques have been developed and applied to the atomic-scale characterization of multi-component nanostructured materials with particular emphasis on the Ni-based superalloys with Platinum Group Metal (PGM) additions. This research has enabled entirely new analysis approaches for solute distribution/segregation analysis, atom probe crystallography, and lattice rectification and has demonstrated potential for converging atomic scale modeling and simulation with atomic resolution microscopy. These findings now sit on the cusp of a renaissance approach in materials design, where Integrated Computational Materials engineering (ICME) can be enabled by real world 3D atomic resolution data via atom probe microscopy.
