Helium swelling in WO3 microcomposites

Ceramics International, 2020
Abstract The paper presents results of helium accumulation processes in structure of the near-surface layer of WO3 microparticles as a result of irradiation with low-energy helium ions He2+ 40 keV. The dependences of changes in morphology of surface layer at irradiation, as well as the structural characteristics of microparticles at irradiation, are ...

Degradation processes and helium swelling in beryllium oxide

Surface and Coatings Technology, 2020
Abstract The work is devoted to the investigation of the processes of defect formation and helium swelling of the surface layer of BeO ceramics upon irradiation with helium ions with fluences of 1 × 1017–5 × 1017 ion/cm2. The choice of the type of ions for irradiation and irradiation fluence is due to the possibility of modeling the processes of ...

On the helium bubble swelling in nano-oxide dispersion-strengthened steels

Journal of Materials Science and Technology, 2022
Abstract The development of structural materials resistant to harsh radiation environments requires an in-depth understanding of the early stage of the aging processes. In radiation environments with high transmutation helium production rates such as in fusion and spallation applications, even materials with otherwise acceptable radiation stability ...

Microstructure change and swelling of helium irradiated beryllium

Fusion Engineering and Design, 2019
Abstract Beryllium, as an outstanding nuclear metal, will be exposed to high-dose irradiation of high-energy neutrons during services in reactor, which will produce a large number of helium and significant irradiation damage resulting in extreme performance degradation.

Bubble Swelling in Ferritic/Martensitic Steels Exposed to Radiation Environment with High Production Rate of Helium

open access: yesMaterials, 2021
Reduced-activativon ferritic/martensitic (RAFM) steels are prospective structural materials for fission/fusion nuclear applications because their radiation and swelling resistance outperforms their austenitic counterparts.

Synthesis and resistance to helium swelling of Li2TiO3 ceramics

Journal of Materials Science: Materials in Electronics, 2020
The work is devoted to the study of the effect of helium ion irradiation on the properties of ceramics based on Li2TiO3, which have great potential as a breeding blanket in the design of thermonuclear reactors. The choice of the type of ions and irradiation doses of 1–5 × 1017 ion/cm2 is due to the possibility of modeling the processes of defect ...

Effect of Helium on Radiation Swelling of SiC

Physica Scripta, 2004
Ceramic materials produced on the basis of SiC and SiC/SiC composites are considered, due to their high-temperature strength, pseudo-ductile fracture behavior and low-induced radioactivity, as candidate materials for fusion reactors. The radiation resistance of ceramic materials under neutron irradiation is one of the key problems, which determines the
