“…Research by Wang et al focused on a larger fluence. The helium bubble diameter in Zr-based metallic glass in their study was approximately 10 times larger than in ours, and blistering, peeling, and flaking did not occur [38]. As a result of the SRIM calculation, the metallic glass Fe 80 Si 7.43 B 12.57 density was 8.4599 × 10 22 atoms/cm 3 , that of metallic glass Ta 38 Ni 62 was 6.7715 × 10 22 atoms/cm 3 , and that of metallic glass Zr 64 Cu 17.8 Ni 10.7 Al 7.5 was 5.3242 × 10 22 atoms/cm 3 .…”

“…The different amount of free volume in the metallic glass made their helium solubility different, thus the helium bubble size was different. Under their respective irradiation conditions, all three types of metallic glass conditions resisted He 2+ ion irradiation better than W. The peak DPA of metallic glass Ta 38 Ni 62 under He 2+ irradiation at 1 × 10 18 ions/cm 2 was 29 dpa, whereas the peak DPA of metallic W was 16 dpa, which was the DPA required for W in the demonstration power plant as the divertor for 5 years [39]. Although the peak DPA of metallic glass was greater than that of W, because of the short-range ordered and long-range disordered structure, metallic glass could not generate lattice defects like the crystal, and ion irradiation damage in metallic glass was smaller than that in the crystal.…”

“…Under the same ion energy and fluence, metallic glass strip Fe 80 Si 7.43 B 12.57 [37] and bulk metallic glass Zr 64 Cu 17.8 Ni 10.7 Al 7.5 [38] also maintained an amorphous state. Helium bubble layers of metallic glass Fe 80 Si 7.43 B 12.57 and Zr 64 Cu 17.8 Ni 10.7 Al 7.5 were located approximately in the depth of the ion range.…”

“…Typically, the arrangement of atoms was amorphous, so the state before irradiation was maintained. 38 Ni 62 before and after irradiation was smooth, without apparent irradiation damage even for maximum fluence. The polishing-induced sunken areas on the metallic W surface became larger at 1 × 10 18 ions/cm 2 .…”

a b s t r a c tMetallic glass Ta 38 Ni 62 strips, metallic W, and V 87.5 Cr 4.17 Ti 4.17 Nb 4.17 alloy were irradiated using a 500 keV He 2+ ion beam at different fluence to compare the metallic glass resistance to irradiation. Metallic glass Ta 38 Ni 62 remained amorphous at different He 2+ irradiation fluence. Transmission electron microscopy analysis revealed the presence of helium bubbles at the end of the range of helium ions in the metallic glass. No significant damage resulted in the metallic glass surface, and the root mean square roughness increased nonlinearly with the increase in fluence. At 1 × 10 18 ions/cm 2 , metallic W appeared in larger sunken areas on the surface and V 87.5 Cr 4.17 Ti 4.17 Nb 4.17 alloy experienced multi-layer flaking. The metallic glass Ta 38 Ni 62 resistance to He 2+ ion beam irradiation was better than that of metallic W, and that of the V 87.5 Cr 4.17 Ti 4.17 Nb 4.17 alloy was the poorest.

Protective corrosion resistant coatings serve for decreasing the amount of ionic contaminants from Havar ® entrance foils of the targets for [ 18 F] production. The corrosion damage of coated entrance foils is caused mainly by the diffusion of highly reactive products of water radiolysis through the protective film towards Havar ® substrate. Since amorphous metal alloys (metallic glasses) are well-known to perform a high corrosion resistance, the glass forming ability, microstructure and diffusion barrier efficiency of binary alloys containing chemically inert Nb, Ta, Zr were investigated. Nb-Ta, Nb-Zr and Ta-Zr films of different alloy composition and ~1.5 μm thickness were co-deposited by magnetron sputtering. Diffusion barrier efficiency tests used reactive aluminum underlayer and protons of acid solution and gallium atoms at elevated temperature as diffusing particles. Though cosputtered Nb-Ta and Nb-Zr alloy films of different contents were crystalline, Ta-Zr alloy was found to form dense amorphous microstructures in a range of composition with 30-73% atomic Ta. The diffusion barrier efficiency of Nb-Zr and Nb-Ta alloy coatings decreased with increase of Nb content. The diffusion barrier efficiency of sputtered Ta-Zr alloy coatings increased with the transition from nanocrystalline columnar microstructure to amorphous for coatings with 30-73% at. Ta.
