摘要：Ar12+ions with the energy of 3 MeV were used to irradiate the metallic glass Al7.5Cu17.8Ni10.7Zr64 and metal tungsten, in order to study the irradiation damage of metallic glasses. The irradiation dos was 1×1014, 1×1015 and 1×1016 ions/cm2, respectively. The XRD analysis showed that Al7.5Cu17.8Ni10.7Zr64 remained amor-phous structure after irradiation exposure to different doses. After irradiation, there was no obvious irradiation damage on the surface of the metallic glass, while a large area of irregular cracks and holes were found on the surface of metal tungsten when the dose is up to 1×1016 ions/cm2. The AFM result showed the surface root-mean-square roughness of Al7.5Cu17.8Ni10.7Zr64 increased with the increase of irradiation doses. The surface hardness of the metallic glass decreased slightly, while the hardness of metal tungsten increased after irradiation. It is concluded that the anti-radiation performance against Ar12+ ions of metallic glass Al7.5Cu17.8Ni10.7Zr64 was better than metal tungsten when irradiated at temperatures below the glass-transition temperature of the metallic glass Al7.5Cu17.8Ni10.7Zr64.
