Solute cluster formation during service is the primary cause of embrittlement in reactor
pressure vessel (RPV) steels. Atom probe tomography (APT) has consistently shown that the …

We summarize the findings from an interlaboratory study conducted between ten
international research groups and investigate the use of the commonly used maximum …

Atom probe tomography (APT) has enabled the direct visualization of solute clusters.
However one of the main analysis methods used by the APT community, ie the maximum …

Atom probe tomography (APT) is a powerful microscopy technique to characterize nano-
sized clusters of the alloying elements in the bulk of reactor pressure vessel (RPV) steels …

Atom probe tomography (APT) is a powerful technique to characterize buried three-
dimensional nanostructures in a variety of materials. Accurate characterization of those …

Isoconcentration surfaces are commonly used to delineate phases in atom probe datasets.
These surfaces then provide the spatial and compositional reference for proximity …

Atom probe tomography, and related methods, probe the composition and the three-
dimensional architecture of materials. The software tools which microscopists use, and how …

Accurate, repeatable and quantitative analysis of nanoscale solute clustering in atom probe
tomography (APT) datasets is a complex challenge which is made more difficult by the …

Ni–Si cluster is a major contributor to the irradiation hardening in irradiated stainless steels.
The heterogeneous nucleation of Ni–Si clusters is associated with radiation-induced …

An automated way to accurately and reproducibly identify edge clusters within atom probe
tomography datasets has been developed. The alpha-hull algorithm is used to generate a …
