Abstrak

After being self-ion implanted at 400 °C and 550 °C, the microstructure and irradiation hardness of kilogram-scale V-4Cr-4Ti alloys were studied using a transmission electron microscope (TEM) and nano-indentation test technology. Irradiation was performed using self-ions (V<sup>2+</sup>) at 2.5 MeV with design influences of 1.15 × 10<sup>15</sup> ions cm<sup>−2</sup>, 4.59 × 10<sup>15</sup> ions cm<sup>−2</sup>, and 9.17 × 10<sup>15</sup> ions cm<sup>−2</sup>, so that the peak damages of V-4Cr-4Ti alloys are 1, 4, and 8 dpa, respectively. Compared with the 400 °C samples, the 550 °C samples exhibited a higher-density number of dislocation loops and increased hardness and reached saturation at lower irradiation doses. The irradiation temperature was mainly responsible for these differences, and the potential mechanism for its effect on the irradiation behavior was discussed.
