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…
Two-dimensional few-atom noble gas clusters in a graphene sandwich
Manuel Längle, Kenichiro Mizohata, Clemens Mangler +4
Van der Waals atomic solids of noble gases on metals at cryogenic temperatures were the first experimental examples of two-dimensional systems. Recently such structures have also b…
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…
Sub-surface alteration and related change in reflectance spectra of space-weathered materials
K. Chrbolková, P. Halodová, T. Kohout +7
One of the main complications for the interpretation of reflectance spectra of airless planetary bodies is surface alteration by space weathering caused by irradiation by solar win…
Thermal diffusivity recovery and defect annealing kinetics of self-ion implanted tungsten probed by insitu Transient Grating Spectroscopy
Abdallah Reza, Guanze He, Cody A. Dennett +3
Tungsten is a promising candidate material for plasma-facing armour components in future fusion reactors. A key concern is irradiation-induced degradation of its normally excellent…
Comparison of space weathering spectral changes induced by solar wind and micrometeoroid impacts using ion- and femtosecond-laser-irradiated olivine and pyroxene
K. Chrbolková, R. Brunetto, J. Ďurech +8
Space weathering is a process that changes the surface of airless planetary bodies. Prime space weathering agents are solar wind irradiation and micrometeoroid bombardment. These p…
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…
Observation of transient and asymptotic driven structural states of tungsten exposed to irradiation
Daniel R. Mason, Suchandrima Das, Peter M. Derlet +8
Combining spatially resolved X-ray Laue diffraction with atomic-scale simulations, we observe how ion-irradiated tungsten undergoes a series of non-linear structural transformation…
Nanoscale lattice strains in self-ion implanted tungsten
N. W. Phillips, H. Yu, S. Das +6
Developing a comprehensive understanding of the modification of material properties by neutron irradiation is important for the design of future fission and fusion power reactors.…
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…
Non-destructive study of collision cascade damage in self-ion irradiated tungsten using HR-EBSD and ECCI
Hongbing Yu, Phani Karamched, Suchandrima Das +3
Understanding defect production and evolution under irradiation is a long-standing multi-scale problem. Conventionally, experimental examination of irradiation-induced defects (IID…
Modified deformation behaviour of self-ion irradiated tungsten: A combined nano-indentation, HR-EBSD and crystal plasticity study
Suchandrima Das, Hongbing Yu, Kenichiro Mizohata +2
Predicting the dramatic changes in material properties caused by irradiation damage is key for the design of future nuclear fission and fusion reactors. Self-ion implantation is an…
Thermal diffusivity degradation and point defect density in self-ion implanted tungsten
Abdallah Reza, Hongbing Yu, Kenichiro Mizohata +1
Using transient grating spectroscopy (TGS) we measure the thermal diffusivity of tungsten exposed to different levels of 20 MeV self-ion irradiation. Damage as low as 3.2 x 10^-4 d…
