Surface damage in ultrafine and multimodal grained tungsten materials induced by low energy helium irradiation
نویسندگان
چکیده
SEMmicrograph of a multimodal grained tungsten material after being irradiated with 200 eV He ions at 950 C and a fluence of 1 10 m 2 showing the detachment and the nanostructuring of the small grains as well as pore formation on top of the nanostructures. The sample was etched before irradiation for better imaging of the grain boundaries. a r t i c l e i n f o

Helium bubble formation in ultrafine and nanocrystalline tungsten under different extreme conditions
We have investigated the effects of helium ion irradiation energy and sample temperature on the performance of grain boundaries as helium sinks in ultrafine grained and nanocrystalline tungsten. Irradiations were performed at displacement and non-displacement energies and at temperatures above and below that required for vacancy migration. Microstructural investigations were performed using Tra...

Gonderman, Sean Robert. M.S.N.E., Purdue University, August 2014. Correlating Grain Size to Radiation Damage Tolerance of Tungsten Materials Exposed to Relevant Fusion Conditions. Major Professor: Jean Paul Allian. Tungsten remains a leading candidate for plasma facing component (PFC) in future fusion devices. This is in large part due to its strong thermal and mechanical properties. The ITER p...
متن کاملDamage studies on irradiated tungsten by helium and argon ions in a plasma focus device
Damage of tungsten due to helium and argon ions of a PF device was studied. Tungsten samples were irradiated by 20 shots of the plasma focus device with argon and helium as working gases, separately. The tungsten surface was analyzed by SEM, before and after irradiation. SEM revealed dense blisters with diameters of a few hundred nanometers, on the samples which were irradiated by helium ions, ...

متن کاملNanostructured fuzz growth on tungsten under low-energy and high-flux He irradiation
We report the formation of wave-like structures and nanostructured fuzzes in the polycrystalline tungsten (W) irradiated with high-flux and low-energy helium (He) ions. From conductive atomic force microscope measurements, we have simultaneously obtained the surface topography and current emission images of the irradiated W materials. Our measurements show that He-enriched and nanostructured st...
