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…

On the role of boron, carbon and zirconium on hot cracking and creep resistance of additively manufactured polycrystalline superalloys

Arthur Després, Stoichko Antonov, Charlotte Mayer +4

We investigate the hot cracking susceptibility and creep resistance of three versions of a nickel-based superalloy with different contents of boron, carbon and zirconium fabricated…

Mechanisms of Ti3Al precipitation in hcp alpha-Ti

Felicity F. Dear, Paraskevas Kontis, Baptiste Gault +3

Nucleation and growth of TiAl \textalpha{} ordered domains in \textalpha{}-Ti--Al--X alloys were characterised using a combination of transmission electron microscopy, atom…

On the coarsening mechanism and deformation of borides under annealing and creep in a polycrystalline superalloy

Lola Lilensten, Aleksander Kostka, Sylvie Lartigue-Korinek +4

We have investigated the coarsening mechanism of intergranular Cr-rich M2B borides after creep and annealing at 850C for approximately 3000 hours in a polycrystalline nickel-based…

Enhanced creep performance in a polycrystalline superalloy driven by atomic-scale phase transformation along planar faults

Lola Lilensten, Stoichko Antonov, Baptiste Gault +2

Predicting the mechanical failure of parts in service requires understanding their deformation behavior, and associated dynamic microstructural evolution up to the near-atomic scal…

Spinodal decomposition versus classical gamma-prime nucleation in a nickel-base superalloy powder: An in-situ neutron diffraction and atomic-scale analysis

David M Collins, Neil D'Souza, Chinnapat Panwisawas +4

Contemporary powder-based polycrystalline nickel-base superalloys inherit microstructures and properties that are heavily determined by the thermo-mechanical treatments during proc…
