Effect of Sn on generalized stacking fault energy surfaces in zirconium and its hydrides
P. Chakraborty, I. Mouton, B. Gault +3
Hydrogen embrittlement in Zr alloy fuel cladding is a primary safety concern for water based nuclear reactors. Here we investigated the stabilisation of planar defects within the f…
Three-dimensional atomically-resolved analytical imaging with a field ion microscope
Shyam Katnagallu, Felipe Felipe F. Morgado, Isabelle Mouton +2
Atom probe tomography (APT) helps elucidate the link between the nanoscale chemical variations and physical properties, but it has limited structural resolution. Field ion microsco…
Hydride growth mechanism in Zircaloy-4: investigation of the partitioning of alloying elements
Isabelle Mouton, Yanhong Chang, Poulami Chakraborty +4
The long-term safety of water-based nuclear reactors relies in part on the reliability of zirconium-based nuclear fuel. Yet the progressive ingress of hydrogen during service makes…
Imaging individual solute atoms at crystalline imperfections in metals
Shyam Katnagallu, Leigh T. Stephenson, Isabelle Mouton +11
Directly imaging all atoms constituting a material and, maybe more importantly, crystalline defects that dictate materials' properties, remains a formidable challenge. Here, we pro…
Atomic-scale investigation of hydrogen distribution in a Ti-Mo alloy
Fengkai Yan, Isabelle Mouton, Leigh T. Stephenson +5
Ingress of hydrogen is often linked to catastrophic failure of Ti-alloys. Here, we quantify the hydrogen distribution in fully \b{eta} and α+\b{eta} Ti-Mo alloys by using atom prob…
Electrical and Optical Properties of Heavily Ge-Doped AlGaN
R. Blasco, A. Ajay, E. Robin +7
We report the effect of germanium as n-type dopant on the electrical and optical properties of AlxGa1-xN layers grown by plasma assisted molecular-beam epitaxy. The Al content has…
Quantification challenges for atom probe tomography of hydrogen and deuterium in Zircaloy-4
Isabelle Mouton, Andrew J. Breen, Siyang Wang +8
Analysis and understanding of the role of hydrogen in metals is a significant challenge for the future of materials science, and this is a clear objective of recent work in the ato…
Atomic scale analysis of grain boundary deuteride growth front in Zircaloy-4
A. J. Breen, I. Mouton, W. Lu +11
Zircaloy-4 (Zr-1.5%Sn-0.2%Fe-0.1%Cr wt. %) was electrochemically charged with deuterium to create deuterides and subsequently analysed with atom probe tomography and scanning trans…
The Laplace project: an integrated suite for correlative atom probe tomography and electron microscopy under cryogenic and UHV conditions
Leigh T. Stephenson, Agnieszka Szczepaniak, Isabelle Mouton +13
We present sample transfer instrumentation and integrated protocols for the preparation and correlative characterization of environmentally-sensitive materials by both atom probe t…
