Swelling and swelling resistance possibilities of austenitic stainless steels in fusion reactors

, 1983
Fusion reactor helium generation rates in stainless steels are intermediate to those found in EBR-II and HFIR, and swelling in fusion reactors may differ from the fission swelling behavior.

Focused helium ion beam nanofabrication by near-surface swelling

Journal of Vacuum Science & Technology B
The focused helium ion beam microscope is a versatile imaging and nanofabrication instrument enabling direct-write lithography with sub-10 nm resolution. Subsurface damage and swelling of substrates due to helium ion implantation is generally unwanted. However, these effects can also be leveraged for specific nanofabrication tasks.

Helium Porosity Formation in Vanadium Alloys of V-Ti-Cr, V-W-Zr and V-W-Ta Systems in Comparison with Binary Alloys

, 2018
Vanadium alloys are considered candidates for use as structural materials of fusion reactors. A large amount of helium will be accumulated in such materials. The presence of helium in the materials may result in gas swelling.

Swelling, microstructural development and helium effects in type 316 stainless steel irradiated in HFIR and EBR-II

, 1981
This work examines the swelling and microstructural development of a single heat of 20%-cold-worked type 316 stainless steel irradiated to produce displacement damage and a high, continuous helium generation rate, in the High Flux Isotope Reactor (HFIR).

Helium effects on neutron-irradiated Cr-Mo ferritic steels: A review of recent results [PDF]

, 1988
Large amounts of transmutation helium will be produced in the first wall of a fusion reactor by the high-energy neutrons from the fusion reaction. Since no fusion reactor is available, the effect of simultaneous helium production and displacement damage ...

Swelling resistance induced by grain refinement and particle dispersion in austenic stainless steel during high energy electron irradiation [PDF]

, 1974
Thin-foils of an austenitic stainless steel with and without dispersions of aluminum oxide particles are irradiated in a High Voltage Electron Microscope at 600°Cs prior to irradiation, up to 1000 ppm of helium atoms are implanted in the thin foils.
