在650 °C下用He离子、He ~+离子和He ~+离子辐照Hastelloy N合金，并使用透射电子显微镜（TEM）和纳米压痕进行检测。透射电镜结果表明，辐照样品中形成了辐照诱导的氦泡、位错环和沉淀物。通过透射电镜照片测量了这些缺陷在峰值损伤区的平均尺寸、数密度及其变化。研究了不同类型的辐照缺陷之间的相互作用，揭示了它们背后的机制。此外，纳米压痕测试表明，在所有的辐照样品的辐照诱导硬化。实验测得的纳米硬度增量（ΔH）表明，He + He离子辐照试样的纳米硬度增量（ΔH）大于He + He离子辐照试样的纳米硬度增量（Δ H），表明He + He离子辐照试样的纳米硬度增量具有协同效应。
The Hastelloy N alloy were irradiated by He ions, Xe ions and Xe + He ions at 650 °C and examined using transmission electron microscopy (TEM) and nano-indentation. TEM results showed the formation of irradiation induced helium bubbles, dislocation loops and precipitates in the irradiated samples. The mean size, number density and their variations of these defects at the peak damage regions were measured through TEM micrographs. The interactions between different types of irradiation induced defects were investigated and the mechanisms behind them have been revealed in this study. In addition, the nanoindentation test showed the irradiation induced hardening in all the irradiated samples. The measured nanohardness increment (ΔH) for sample irradiated by Xe + He ions was larger than that of the combined single ion irradiation case, indicating the presence of synergistic effect in the hardening of the both ions irradiated sample.
