abstract = {We employed correlative atom probe tomography (APT) and
transmission electron microscopy (TEM) to analyze the
alumina scale thermally grown on the oxide
dispersion-strengthened alloy MA956. Segregation of Ti and Y
and associated variation in metal/oxygen stoichiometry at
the grain boundaries and triple junctions of alumina were
quantified and discussed with respect to the oxidation
behavior of the alloy, in particular, to the formation of
cation vacancies. Correlative TEM analysis was helpful to
avoid building pragmatically well-looking but substantially
incorrect APT reconstructions, which can result in erroneous
quantification of segregating species, and highlights the
need to consider ionic volumes and detection efficiency in
the reconstruction routine. We also demonstrate a
cost-efficient, robust, and easy-handling setup for
correlative analysis based solely on commercially available
components, which can be used with all conventional TEM
tools without the need to modify the specimen holder
assembly.},
