Two new, low activation high entropy alloys (HEAs) TiVZrTa and TiVCrTa are studied for use as in-core, structural nuclear materials for in-core nuclear applications. Low-activation is a desirable property for nuclear reactors, in an attempt to reduce

All-solid-state batteries with a Li anode and ceramic electrolyte have the potential to deliver a step change in performance compared with today’s Li-ion batteries1,2. However, Li dendrites (filaments) form on charging at practical rates and penetr

In this study, we have investigated the microstructure and mechanical properties of two refractory high entropy alloys (RHEAs), Ti-V-Cr5-Nb-Ta and Ti-V-Cr-Nb-Ta, in their as-cast and heat-treated conditions. Both alloys show almost single-phase BCC s

The measurement of mechanical properties at the microscale is of interest across a wide range of engineering applications. Much recent work has demonstrated that micropillar compression can be used to measure changes in flow properties at temperature

The fracture behaviour of individual grain boundaries has been studied in order to understand the mechanisms controlling stress corrosion cracking in nuclear reactors. In particular, the role of oxidation in facilitating crack initiation and propagat

Model alloys have been made of pure W and 1% & 5% W-Ta and W-Re. Indentation hardness and modulus data were obtained by nanoindentation to assess the effect of composition on mechanical properties. Results showed that both the Ta and Re compositions

CrMnFeCoNi, also known as the Cantor alloy, exhibits attractive mechanical properties at cryogenic temperatures and encouraging irradiation resistance. This thesis uses electron backscatter diffraction (EBSD), (scanning) transmission electron microsc

Nuclear fission power is a reliable and zero carbondioxide emitting energy source and nuclear fusion is regarded as the ultimate terrestrial energy source. Both pro cesses require radiation resistant structural reactor core materials. Atom probe

In this work refractory High-Entropy Alloys (HEAs) have been investigated for application as Plasma Facing Components in nuclear fusion reactors. Sample fabrication was guided by optimising composition in order to maximise the Ω parameter, which ha

There is significant interest in defining and quantifying the performance of polycrystalline Ni-based superalloys – particularly high strength ones produced via powder processing for turbine disc applications – at temperatures between 700 and 800
