Direct Imaging of Hydrogen-Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain
David Yang, Mujan Seif, Guanze He +9
Hydrogen embrittlement (HE) poses a significant challenge to the durability of materials used in hydrogen production and utilization. Disentangling the competing nanoscale mechanis…
Deformation Localisation in Ion-Irradiated FeCr
Kay Song, Dina Sheyfer, Wenjun Liu +6
Irradiation-induced ductility loss is a major concern facing structural steels in next-generation nuclear reactors. Currently, the mechanisms for this are unclear but crucial to ad…
Microstructural and material property changes in severely deformed Eurofer-97
Kay Song, Guanze He, Abdallah Reza +7
Severe plastic deformation changes the microstructure and properties of steels, which may be favourable for their use in structural components of nuclear reactors. In this study, h…
Dose and compositional dependence of irradiation-induced property change in FeCr
Kay Song, Dina Sheyfer, Kenichiro Mizohata +8
Ferritic/martensitic steels will be used as structural components in next generation nuclear reactors. Their successful operation relies on an understanding of irradiation-induced…
The Effect of High Pressure Torsion on Irradiation Hardening of Eurofer-97
Gregory Strangward-Pryce, Kay Song, Kenichiro Mizohata +1
We investigated the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97. Material was deformed to shear strains from 0 to ~230, a…
Refinements for Bragg coherent X-ray diffraction imaging: Electron backscatter diffraction alignment and strain field computation
David Yang, Mark T. Lapington, Guanze He +8
Bragg coherent X-ray diffraction imaging (BCDI) allows the three-dimensional (3D) measurement of lattice strain along the scattering vector for specific microcrystals. If at least…
In situ Bragg coherent X-ray diffraction imaging of corrosion in a Co-Fe alloy microcrystal
David Yang, Nicholas W. Phillips, Kay Song +5
Corrosion is a major concern for many industries, as corrosive environments can induce structural and morphological changes that lead to material dissolution and accelerate materia…
Deformation Behaviour of Ion-Irradiated FeCr: A Nanoindentation Study
Kay Song, Hongbing Yu, Phani Karamched +3
Understanding the mechanisms of plasticity in structural steels is essential for the operation of next-generation fusion reactors. Elemental composition, particularly the amount of…
Annealing of focused ion beam damage in gold microcrystals: An in situ Bragg coherent X-ray diffraction imaging study
David Yang, Nicholas W. Phillips, Kay Song +3
Focused ion beam (FIB) techniques are commonly used to machine, analyse and image materials at the micro- and nanoscale. However, FIB modifies the integrity of the sample by creati…
Characterising Ion-Irradiated FeCr: Hardness, Thermal Diffusivity and Lattice Strain
Kay Song, Suchandrima Das, Abdallah Reza +6
Ion-irradiated FeCr alloys are useful for understanding and predicting neutron-damage in the structural steels of future nuclear reactors. Previous studies have largely focused on…
