Elastic Strain Associated with Irradiation-Induced Defects in Self-ion Irradiated Tungsten
Guanze He, Hongbing Yu, Phani Karamched +2
Elastic interactions play an important role in controlling irradiation damage evolution, but remain largely unexplored experimentally. Using transmission electron microscopy (TEM)…
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…
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…
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…
