Engineering Alloys
Our research team explores the behaviour, processing, microstructure and performance of alloys for industries such as aerospace, nuclear power generation, large scale industrial processes, and microelectronics. This work addresses challenges such as: reduction in CO2 generation, development and manufacture of lighter and higher performance alloys; improvements in safety and lifetime prediction through physical understanding of deformation processes; and significant improvements in the life cycle of alloys, reducing energy consumption through reuse and recycling.

Engineering Alloys Staff
Dr Ben Britton
Dr Ben Britton is a Senior Lecturer and RAEng Research Fellow in the Department of Materials at Imperial College London.
His research focusses on understanding materials in high-value high-risk environments, for instance in aerospace, nuclear power and oil & gas applications. His research interests include experimental techniques such as electron backscatter diffraction (EBSD), digital image correlation (DIC), micro-mechanical test (e.g. nanoindentation, micropillar compression), as well as simulation with crystal plasticity and dislocation dynamics. This work focusses on the behaviour of hexagonal and cubic metals (e.g. Zr, Ti, Cu, Ni, Fe).
