研究领域

My group is concerned with the mechanical behaviour of materials, mostly metals and alloys, at the microstructural level. We are at the forefront of developing the SEM based EBSD technique for mapping stress distributions at high spatial resolution. Other techniques used extensively within the group are nano-indentation, micro-cantilever bend testing and micro-pillar compression testing, digital image correlation and dislocation-based modelling. We aim to help improve mechanistic understanding of deformation, fracture and fatigue processes in metals and alloys. Currently we are working on Ti, Cu, Ni, Fe-Cr and W based alloys.
