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…
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…
Transient grating spectroscopy: An ultrarapid, nondestructive materials evaluation technique
Felix Hofmann, Michael P. Short, Cody A. Dennett
Structure-property relationships are the foundation of materials science. Linking microstructure and material properties is essential for predicting material response to driving fo…
Surface terraces in pure tungsten formed by high-temperature oxidation
Hongbing Yu, Suchandrima Das, Junliang Liu +2
We observe large-scale surface terraces in tungsten oxidised at high temperature and in high vacuum. Their formation is highly dependent on crystal orientation, with only {111} gra…
Mapping data between sample and detector conjugated spaces in Bragg coherent diffraction imaging
David Yang, Nicholas W. Phillips, Felix Hofmann
Bragg coherent X-ray diffraction imaging (BCDI) is a non-destructive, lensless method for 3D-resolved, nanoscale strain imaging in micro-crystals. A challenge, particularly for new…
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…
Transient grating spectroscopy of thermal diffusivity degradation in deuterium implanted tungsten
Abdallah Reza, Yevhen Zayachuk, Hongbing Yu +1
Using transient grating spectroscopy, we measure thermal diffusivity and surface acoustic wave speed in tungsten exposed to different fluences of deuterium plasma. Scanning electro…
Nano-scale imaging of the full strain tensor of specific dislocations extracted from a bulk sample
Felix Hofmann, Nicholas W. Phillips, Suchandrima Das +5
Lattice defects play a key role in determining the properties of crystalline materials. Probing the 3D lattice strains that govern their interactions remains a challenge. Bragg Coh…
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…
