Principal Investigator:

  • Dr Ben Britton, CSci, CEng, FIMMM, DPhil Oxford (2010), MEng Oxford (2007)

Senior Lecturer / RAEng Research Fellow

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.

PhD Candidate Researchers:

  • Simon Wyatt

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 and electron backscatter diffraction (EBSD).
