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…
