Reflections on the analysis of interfaces and grain boundaries by Atom Probe Tomography

distribution of the atoms in the plane of the interface with added iso composition

Dr Benjamin Jenkins, Dr Paul Bagot and Professor Michael Moody, with colleagues based in CNRS, Max-Planck Institute and Imperial College, present this critical perspective on key aspects pertaining to spatial resolution limits and the issues with compositional analysis that can limit the quantification of interface measurements.

 

Published in Microscopy and Analysis, this paper provides a comprehensive review which incorporated a steel sample, although the results can be applied to a wide range of industrially relevant engineering materials.
