在这项研究中，我们研究了铁离子辐照RAFM钢（SIMP）在高温蒸汽中的加速腐蚀行为。研究了氧化膜的厚度、元素组成、表面形貌、晶体结构和显微结构。与未经辐照的样品一致，辐照样品的氧化膜由外层的Fe 3 O 4、多孔的Fe-Cr尖晶石内层和由（Cr，Si）2 O3组成的内部氧化物区组成。氧化膜的厚度随着位移损伤的增加而增加。与奥氏体钢相比，位移损伤对SIMP钢腐蚀速率的增加较为温和。
In this study we investigated the accelerated corrosion behavior of Fe-ion irradiated RAFM steel (SIMP) in high-temperature steam. The thickness, elementary composition, surface morphology, crystal structure and microstructure of the formed oxide films were studied. Consistent with the unirradiated sample, the oxide films of the irradiated samples consisted of an outer layer of Fe3O4, a porous inner layer of Fe-Cr spinel, and an internal oxide zone composed of (Cr, Si)2O3. The thickness of the oxide films increased with the increasing displacement damage. Compared with austenitic steels, the increase of corrosion rate of SIMP steel by displacement damage is rather moderate.
