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…
Dislocation density distribution at slip band-grain boundary intersections
Yi Guo, David M. Collins, Edmund Tarleton +3
We study the mechanisms of slip transfer at a grain boundary, in titanium, using Differential Aperture X-ray Laue Micro-diffraction (DAXM). This 3D characterization tool enables me…
The influence of hydrogen core force shielding on dislocation junctions in iron
Haiyang Yu, Ivaylo H. Katzarov, Anthony T. Paxton +2
The influence of hydrogen on dislocation junctions was analysed by incorporating a hydrogen dependent core force into nodal based discrete dislocation dynamics. Hydrogen reduces th…
Orientation-dependent indentation response of helium-implanted tungsten
Suchandrima Das, Hongbing Yu, Edmund Tarleton +1
A literature review of studies investigating the topography of nano-indents in ion-implanted materials reveals seemingly inconsistent observations, with report of both pile-up and…
Hardening and Strain Localisation in Helium-Ion-Implanted Tungsten
Suchandrima Das, Hongbing Yu, Edmund Tarleton +1
Tungsten is the main candidate material for plasma-facing armour components in future fusion reactors. In-service, fusion neutron irradiation creates lattice defects through collis…
