Abstract
The protons with an energy of 250â¯keV were used to irradiate metallic glass Ni62Ta38 and metal W, the changes in structure and surface morphology of both the materials were compared, and their performances against the irradiation were evaluated, in order to provide the reference for the possibility of application of metallic glass Ni62Ta38 in irradiation environment. The results showed that after the proton irradiation, metallic glass Ni62Ta38 still maintained its good amorphousness without obvious irradiation damage on its surface. Meanwhile, stress was generated in metal W, and its crystalline size, micro-strain and dislocation line density varied undulately with the increase of fluence. When the irradiation fluence was 1.0â¯Ãâ¯1018â¯ions/cm2, large area of blisters were formed on the surface of metal W. The surface roughness of metal W increased with the fluence. Compared with metal W, the proton irradiation resistance of metallic glass Ni62Ta38 was better.
