Atom probe tomography (APT) is an analytical technique that provides quantitative three‐
dimensional elemental and isotopic analyses at sub‐nanometre resolution across the whole …

Prediction of material performance in fusion reactor environments relies on computational
modelling, and will continue to do so until the first generation of fusion power plants come on …

Atom probe tomography (APT) is routinely used for analyzing property-enhancing particles
in the nanometer-size range and below, and plays a prominent role in the analysis of solute …

Embrittlement of light water reactor pressure vessel (RPV) steels by fast neutron irradiation
may limit extended nuclear plant life. Embrittlement, which is manifested as increases in …

Abstract High-entropy alloys (HEAs), also called multi-principal-elements alloys, possess
extraordinary mechanical properties, including high strength and hardness, thermal stability …

When a supersaturated Al solid solution is held at room temperature, natural ageing occurs
through the formation of clusters/zones providing a strengthening of the material. Recently, it …

Irradiation can induce microscopic defects in reactor pressure vessel (RPV) steel, resulting
in macroscopic hardening and embrittlement. This paper proposes a micro‑meso …

Abstract Ferritic Oxides Dispersion Strengthened (ODS) steels are of great interest for
nuclear fission and fusion power plants. The nano-oxides embedded into the matrix provide …

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 …

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 …
