Strain localisation and failure at twin-boundary complexions in nickel-based superalloys
Nature Communications, 2020 Twin boundaries (TBs) in Ni-based superalloys are vulnerable sites for failure in demanding environments, and a current lack of mechanistic understanding hampers the reliable lifetime prediction and performance optimisation of these alloys.

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Effect of alloying elements on the γ’ antiphase boundary energy in Ni-base superalloys
Intermetallics (Barking), 2020 Mechanical and fatigue performance of γ-γ′ Ni-base superalloys are strongly affected by the antiphase boundary energy (APBE) of the γ′ precipitates which, in turn, is dictated by the alloy's composition.
