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.

Suki focuses on understanding the performance of metallic composite materials and coatings for use in aeroengine turbines. He is developing understanding of very high spatial resolution mechanical tests of multicomponent microstructures with a view to informing fundamental microstructure-mechanical property relationships for use in crystal plasticity finite element models.

Research Assistant & PhD Candidate
Tianhong is developing new in-situ approaches to understand deformation and failure of solder materials, used in microelectronic devices.
In-situ SEM, EBSD, creep testing, lead free solders
William focusses on understanding the consequences of hydrogen on the micromechanics of steels, particular for energy storage applications. He is developing dislocation dynamics models to understand solute-dislocation interactions.
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.
fast Fourier transform based crystal plasticity modelling; texture; residual stress
Jim is focussing on sour gass - high strength steel interactions for oil&gas applications. Our particular focus is on developing fundamental understanding of the combined effects of chemistry, microstructure and stress on failure of steels with a hope of developing understanding towards the introduction of new steel alloys.

Xinping is focussing on strain partitioning in dual phase titanium alloys for aerospace applications.
Metallography, titanium alloys
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.
Metallography, image analysis, microscopy, deformation
Chris's project focuses on understanding surface degradation in Ni-based alloys.
