Determining the Fundamental Failure Modes in Ni-rich Lithium Ion Battery Cathodes
Siyang Wang, Zonghao Shen, Aigerim Omirkhan +3
Challenges associated with in-service mechanical degradation of Li-ion battery cathodes has prompted a transition from polycrystalline to single crystal cathode materials. Whilst f…
Shear and delamination behaviour of basal planes in Zr3AlC2 MAX phase studied by micromechanical testing
Siyang Wang, Oriol Gavalda-Diaz, Jack Lyons +1
The mechanical properties of layered, hexagonal-structured MAX phases often show the combined merits of metals and ceramics, making them promising material candidates for safety cr…
Fracture properties of La(Fe,Mn,Si)13 magnetocaloric materials
Siyang Wang, Paul Burdett, Edmund Lovell +4
La(Fe,Mn,Si)13 alloys are a promising material family for magnetic refrigeration. Challenges associated with their structural integrity during device assembly and operation require…
The effect of hydrogen on the multiscale mechanical behaviour of a La(Fe,Mn,Si)13-based magnetocaloric material
Siyang Wang, Oriol Gavalda-Diaz, Ting Luo +6
Magnetocaloric cooling offers the potential to improve the efficiency of refrigeration devices and hence cut the significant CO2 emissions associated with cooling processes. A crit…
Environment-assisted crack nucleation in La(Fe,Mn,Si)13-based magnetocaloric materials
Siyang Wang, Edmund Lovell, Liya Guo +3
Cracking in La(Fe,Si)13-based magnetocaloric materials has been observed to predominantly form around La-rich (La2O3) particles and pose a threat to their long-term structural inte…
Nanoscale characterisation of hydrides and secondary phase particles in Zircaloy-4
Wenjun Lu, Paraskevas Kontis, Siyang Wang +4
The interaction of hydrogen and metals continues to be industrially relevant and is a critical part of creating and supporting a safety case for nuclear reactor operation. In the p…
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…
Slip-hydride interactions in Zircaloy-4: Multiscale mechanical testing and characterisation
Siyang Wang, Finn Giuliani, T. Ben Britton
The interactions between δ-hydrides and plastic slip in a commercial zirconium alloy, Zircaloy-4, under stress were studied using in situ secondary electron microscope (SEM) microp…
The effect of δ-hydride on the micromechanical deformation of Zircaloy-4 studied by in situ high angular resolution electron backscatter diffraction
Siyang Wang, Szilvia Kalácska, Xavier Maeder +3
Zircaloy-4 is used extensively as nuclear fuel cladding materials and hydride embrittlement is a major failure mechanism. To explore the effect of δ-hydride on plastic deformation…
Microstructure and formation mechanisms of δ-hydrides in variable grain size Zircaloy-4 studied by electron backscatter diffraction
Siyang Wang, Finn Giuliani, T. Ben Britton
Microstructure and crystallography of δ phase hydrides in as-received fine grain and 'blocky' alpha large grain Zircaloy-4 (average grain size ~11 μm and >200 μm, respectively) wer…
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…
The effect of cooling rate and grain size on hydride formation in Zircaloy-4
Ruth Birch, Siyang Wang, Vivian Tong +1
We explore the distribution, morphology and structure of zirconium hydrides formed using different cooling rates through the solid state Zr+[H] --> Zr + hydride transus, in fine an…
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…
