The evolution processes of the defects in Ni, Ni-Cr and Ni-Mo alloys under 400 keV Ne ion irradiation at different temperatures were investigated. At room temperature, the defect sizes are between 2 and 4 nm and defect densities are in the range of 1.24 × 10¹⁵–1.39 × 10¹⁵ m⁻². With increasing irradiation temperature, the defect sizes become larger, and the defect densities decrease. Moreover, under irradiation at high temperature, Ni-Mo and Ni-Cr alloys show the higher defect densities and smaller defect sizes than Ni. These are ascribed to the pinning effects of solid solution elements on the ion irradiation-induced defects in the nickel-based alloys.

研究了在不同温度下400 keV Ne离子辐照下Ni，Ni-Cr和Ni-Mo合金中缺陷的演变过程。在室温下，缺陷尺寸在2-4 nm之间，缺陷密度在1.24×10 ¹⁵ –1.39×10 ¹⁵ m ^{-2的范围内}。随着照射温度的升高，缺陷尺寸变大，并且缺陷密度降低。而且，在高温下，Ni-Mo和Ni-Cr合金比Ni具有更高的缺陷密度和更小的缺陷尺寸。这些归因于固溶元素对镍基合金中离子辐照引起的缺陷的钉扎作用。
