novel methods for recording stress strain curves in proton Irradiated Material
Scientific Reports, 2020Co-Authors: Albert Smith, Alistair Garner, Jack Donoghue, David Lunt, Allan Harte, Keith Wilford, P J Withers, Michael PreussAbstract:Proton irradiation is often used as a proxy for neutron irradiation but the Irradiated layer is typically <50 μm deep; this presents a problem when trying to obtain mechanical test data as a function of irradiation level. Two novel methodologies have been developed to record stress-strain curves for thin proton-Irradiated surface layers of SA-508-4N ferritic steel. In the first case, in-situ loading experiments are carried out using a combination of X-ray diffraction and digital image correlation on the near surface region in order to measure stress and strain, thereby eliminating the influence of the non-Irradiated volume. The second approach is to manufacture small-scale tensile specimens containing only the proton Irradiated volume but approaching the smallest representative volume of the Material. This is achieved by high-speed focused ion beam (FIB) milling though the application of a Xe+ Plasma-FIB (PFIB). It is demonstrated that both techniques are capable of recording the early stage of uniaxial flow behaviour of the Irradiated Material with sufficient accuracy providing a measure of irradiation-induced shift of yield strength, strain hardening and tensile strength.

high resolution crystallographic and chemical characterisation of iodine induced stress corrosion crack tips formed in Irradiated and non Irradiated zirconium alloys
Journal of Nuclear Materials, 2019Co-Authors: Conor Gillen, Alistair Garner, Pia Tejland, Chris Jones, Katie L Moore, Philipp FrankelAbstract:Abstract High resolution crystallographic and chemical analysis has been performed on iodine-induced stress corrosion crack tips taken from Irradiated and non-Irradiated zirconium alloys. Defuelled cladding tubes were subjected to mandrel testing and subsequent analysis of the crack tip region showed the predominance of transgranular cracking on non-basal planes for the first time in Irradiated Material. In a separate mandrel-tested crack tip sample, iodine was unambiguously identified in the crack tip region using both STEM-EDX and NanoSIMS. For comparison, non-Irradiated C-ring samples were subjected to testing in iodine-ethanol solution, subsequent crack tip analysis showed large levels of intergranular attack and no significant iodine segregation.
