“…Under thermal annealing at temperatures around 750 K, crystalline decomposition products such as NiZr 2 , CuZr 2 and Cu 10 Zr 7 phases have been observed [22]. Due to its wide supercooled liquid region, amorphous Zr 55 Cu 30 Al 10-Ni 5 has been reported to be stable under electron irradiation [27]. However, its stability under ion irradiation is controversial.…”

“…A wider supercooled liquid region for the metallic glass indicates higher thermal stability against crystallization. 15 The metallic glass Fe80Si7.43B12.57 is unstable, and hence its glass transition temperature cannot be measured definitely, whereas Ni62Ta38 is stable and has a wide supercooled liquid region (63 K 16 ).…”

In this study, use of 40-keV H + ion for irradiating metallic glass Fe80Si7.43B12.57 and Ni62Ta38 as well as metallic tungsten (W) at fluences of 1 × 10 18 and 3 × 10 18 ions/cm 2 , respectively, was investigated. At the fluence of 1 × 10 18 ions/cm 2 , a crystalline layer appeared in metallic glass Fe80Si7.43B12.57, with -Fe as the major crystalline phase, coupled with a little Fe2B, Fe3B, and metastable β-Mn-type phase. Fe80Si7.43B12.57 exhibited good soft magnetic properties after irradiation. At the fluence of 3 × 10 18 ions/cm 2 , Ni62Ta38 was found to be amorphous-based, with a little -NiTa and Ni3Ta phases. No significant irradiation damage phenomenon appeared in metallic glasses Fe80Si7.43B12.57 and Ni62Ta38. Blistering, flaking, and other damage occurred on the surface of metallic W, and the root-mean-square (RMS) roughness increased with the increase of fluence. Metallic glass Ni62Ta38 exhibited better resistance to H + irradiation than Fe80Si7.43B12.57, both of which were superior to the metallic W.
