Abstract: High intensity pulsed ion beam(HIPIB) technology was used for simulating the transient heat load conditions of fusion reactor. The ion beam was mainly composed of Cn+(70%) and H+(30%) at an acceleration voltage of 250 kV. We investigated the changing rule of the structure and performance and damaged behavior of metallic glass Zr53Al23.5Cu5.9Co17.6 and W metal under different number of pulses. XRD analysis showed that the metallic glass remained making amorphous phase as its main structure after HIPIB irradiation, while stress were produced in W metal. SEM analysis concluded that there was no apparent irradiation damage on the surface of metallic glass and W metal when the irradiation frequency was 3 and 10 times. While the irradiation
frequency increased to 100 and 300 times, “petal”-shaped and balls appeared on the surface of metallic glass, and cracks appeared on the surface of W. Nanoindentor showed that nano-hardness for the surface of metallic glass after irradiation reduced gradually with the increase of the frequency of irradiation. Zr-based metallic glass had a better resistance under HIPIB irradiation. The buffering capacity of Zr-based metallic glass in connection with
HIPIB irradiation-induced thermal stress is superior to W metal.
