Kay is working on studying irradiation damage on iron-based alloys which are used as the structural components of future nuclear fusion reactors. Our current understanding of the underlying irradiation damage mechanism is still quite poor, particularly at the atomic scale. It is important to understand the microscopic behaviour of defects and their accumulation which causes local volumetric expansion in materials, as this affects the stresses, strains and material properties at the macroscopic scale.
Kay is using X-ray micro-diffraction from synchrotron light sources to measure the irradiation-induced lattice swelling in iron-based alloys. These measurements will then be linked to underlying defects observed using transmission electron microscopy. The effect of these defects on mechanical and thermal transport properties of the material will be investigated with nano-indentation and laser-induced transient grating techniques.
