Thomas graduated in 2017 from the University of Cambridge, with an MSci project in the physical metallurgy of high-entropy alloys. His PhD investigates deformation mechanisms in novel Co/Ni-base dual phase polycrystalline superalloys for use in jet engines, in collaboration with Rolls-Royce. This involves observing dislocations and stacking faults during creep via TEM, and measuring their energies. Grain boundary sliding and microstructural changes will be characterised using EBSD, SEM and DIC. Understanding the effect of stress, temperature and composition on these behaviours will be used to develop and optimise mechanical properties.
