Ben focuses on getting to the bottom of the strength - property - performance relationship of real alloys used in high value engineering applications such as nuclear power, aerospace, and oil & gas applications. He combines a range of appropriate techniques, such as digital image correlation, electron backscatter diffraction and micro-mechanical testing to understand processes such as fatigue crack initiation, plastic deformation and microstructural evolution in metallic and metallic / ceramic materials.

Electron backscatter diffraction; digital image correlation; micromechanical testing; microstructural characterisation; crystal plasticity modelling.

PhD Candidate

Simon is developing new understanding of micromechanical deformation and texture evolution of two phase (hexagonal + body centred cubic) alloys, which are commonly used in aerospace and nuclear industries. This work is achieved through the combination of crystal plasticity FFT modelling, electron backscatter diffraction (EBSD) and neutron diffraction experiments. Simon is a user of DAMASK and is developing code to be included in a future release.

MSci (Cambridge)

PhD candidate

This project investigates deformation mechanisms to aid development of novel Co/NI-based dual phase polycrystalline superalloys for use in jet engines, in collaboration with Rolls-Royce. Grain boundary sliding and microstructural changes will be studied using EBSD, SEM and DIC. This will be combined with dislocation / stacking fault TEM analysis of the effects of stress, temperature and composition.
