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 ...

Swelling of SiC under helium implantation

Journal of Applied Physics, 2005
Single crystals 4H-SiC were implanted with 50 keV helium ions at temperatures up to 600 °C and fluences in the range 1×1016–1×1017cm−2. The helium implantation-induced swelling was studied through the measurement of the step height. The different contributions of swelling were determined by combining simulations of x-ray diffraction curves and ...

Helium bubble formation and swelling in metals

Journal of Nuclear Materials, 1981
Abstract The effect of a continuous production of helium on swelling is analyzed using an improved equation of state for gaseous helium that incorporates both a gas-kinetic as well as a static pressure for densely packed helium. In the absence of a bias, bubble swelling is characterized by two temperature regimes.

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
