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…
On the segregation of Re at dislocations in the γ' phase of Ni-based single crystal superalloys
Xiaoxiang Wu, Surendra Kumar Makineni, Paraskevas Kontis +4
We report evidence of Re and Mo segregation (up to 2.6 at.% and 1 at.%) along with Cr and Co to the dislocations inside of γ' precipitates in a second generation Ni-based single cr…
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…
Segregation assisted grain boundary precipitation in a model Al-Zn-Mg-Cu alloy
Huan Zhao, Frédéric De Geuser, Alisson Kwiatkowski da Silva +4
Understanding the composition evolution of grain boundaries and grain boundary precipitation at near-atomic scale in aluminum alloys is crucial to tailor mechanical properties and…
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…
Parameter free quantitative analysis of atom probe data by correlation functions: Application to the precipitation in Al-Zn-Mg-Cu
Huan Zhao, Baptiste Gault, Dirk Ponge +2
Atom probe tomography enables precise quantification of the composition of second phase particles from their early stages, leading to improved understanding of the thermodynamic an…
