Influence of Helium-Generated Interstitial in Dual Ion Irradiations

, 1985
Simulation of neutron-induced swelling by dual ion irradiation is influenced very strongly by the presence of injected interstitials due to self ions. Co-injected helium also generates extra interstitials, with its influence on void nucleation magnified ...

Superior radiation resistance of ODS-RAFM steels revealed by Positron annihilation spectroscopy study

Journal of Materials Research and Technology
Oxide-dispersion-strengthened (ODS) reduced-activation ferritic/martensitic (RAFM) steels are considered as most promising structural materials for fusion reactors and other advanced nuclear systems due to its excellent irradiation resistance under high ...

Saturation of Proton-Induced Swelling in AISI 316

, 1983
There is some evidence which suggests that void swelling may not increase continuously with increasing irradiation but may saturate at a level dependent on irradiation conditions, helium/dpa level or artifacts of the simulation such as the presence of ...

Swelling damage characteristics induced by CO2 adsorption in shale: Experimental and modeling approaches

Journal of Rock Mechanics and Geotechnical Engineering
Carbon dioxide (CO2) geological sequestration represents a critical technology in mitigating climate change. Shale reservoirs demonstrate a pronounced affinity for CO2, resulting in adsorption-induced swelling that significantly impacts permeability ...

Control of helium effects in irradiated materials based on theory and experiment [PDF]

, 1986
Helium produced in materials by (n,..cap alpha..) transmutation reactions during neutron irradiations or subjected in ion bombardment experiments causes substantial changes in the response to displacement damage.

The Lithium Shell Effect and It\u27s Impact on Microscopy Determinations of Swelling Behavior

, 1984
The heterogeneity of swelling in some irradiated alloys arises from localized enhancement of void nucleation by the lithium shell effect near boron-rich precipitates.
