“…Ion irradiation is widely used to simulate neutron irradiation, which has the advantages of a short time, high damage level, and no radioactivity. Heavy ions (such as Fe 10+ , Cu 2+ , and Ni 2+ ) were mostly used to investigate the irradiation of vanadium alloys to obtain a higher damage dose [12][13][14]. However, the lattice parameters of these ions and V Metals 2021, 11, 1024 2 of 10 are mismatching, which may lead to an experimental phenomenon deviating from the real situation.…”

Microstructure and irradiation hardening of V-4Cr-4Ti alloys with different yttrium (Y) contents were studied by self-ion irradiation at 550 °C via TEM and nano-indentation test technology. The peak damage of the V-4Cr-4Ti-xY alloy (x = 0, 0.1, 0.5, and 1, wt.%) irradiated by 2.5 MeV self-ion (V2+) is 8 dpa. Dense dislocation loops were observed in all vanadium alloy samples after irradiation. With the increase of Y content, both average size and number density of dislocation loops using g = <110> near the pole [001] decreased, while the irradiation hardness increment first decreased and then increased. In order to better reduce the irradiation hardening, it is considered that the addition of 0.1 wt.% Y in V-4Cr-4Ti alloy is reasonable.
