利用离子加速器将氢离子注入ＪＦＭＳ合金试样，在超高压电子显微镜下进行电子辐照，对辐照空洞的形成过程进行原位观察，模拟研究了核反应（ｎ，ｐ）生成的氢对材料辐照肿胀的影响．实验结果表明，注氢主要对辐照空洞的形核产生促进作用，并由此促进材料的辐照肿胀．在５７０Ｋ辐照时，氢的这一促进辐照空洞形核的作用尚不十分明显，随着辐照温度的升高其作用逐渐增强．在６７０Ｋ辐照时，注氢可使辐照空洞的数密度增加一个数量级，材料的辐照肿胀率增加４倍左右．
Hydrogen ions were implanted into the JFMS alloy by ion accelerator and irradiated by EHV electron microscope. The formation process of the irradiation hole was observed in situ. The effect of hydrogen generated by nuclear reaction (n, p) According to the impact of swelling. The experimental results show that the hydrogen injection mainly promotes the nucleation of irradiation holes, and thus promotes the irradiation swelling of the material. At 570K, the role of hydrogen in promoting the formation of irradiated hollow nuclei is not yet apparent, and its effect increases with increasing irradiation temperature. At 670K, hydrogen injection can increase the number density of irradiated cavities by an order of magnitude and increase the irradiated swelling rate of the material by about 4 times.
