Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious…
Zirconium alloys (Zr) are used in the nuclear industry in components present in light- and heavy-water reactors cores. Zr alloys experience corrosion, which is thought to be minimised by adding alloying elements such as iron (Fe), chromium (Cr), and nickel (Ni). This leads to th…
This thesis describes an investigation into how the interaction of protons with microstructural features in Zr and Zr alloys may affect the amount of irradiation damage created in proton-irradiated materials compared with neutron-irradiated materials. Three key microstructural f…
The evolution of materials at an atomistic level may have vital consequences for the properties of materials. Therefore, modelling long time scale behaviour of defects in a material is very important, particularly for those used in nuclear power plants. The materials used in nuc…
An investigation into the processes taking place at the surface interface of ferroelectric Pb(Zr1-x,Tix)O3 immersed in metal salt solution under ultraviolet illumination is presented. The semiconducting and switchable dipolar nature of this material allows the spatial separation…
