Abstract
Metallic glass Ta38Ni62 strips, metallic W, and V87.5Cr4.17Ti4.17Nb4.17 alloy were irradiated using a 500Â keV He2+ ion beam at different fluence to compare the metallic glass resistance to irradiation. Metallic glass Ta38Ni62 remained amorphous at different He2+ 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 1Â ÃÂ 1018 ions/cm2, metallic W appeared in larger sunken areas on the surface and V87.5Cr4.17Ti4.17Nb4.17 alloy experienced multi-layer flaking. The metallic glass Ta38Ni62 resistance to He2+ ion beam irradiation was better than that of metallic W, and that of the V87.5Cr4.17Ti4.17Nb4.17 alloy was the poorest.
