The corrosion characteristics of 12Cr2W2Mn Ferritic/martensitic (F/M) steel before and after Au-ions irradiation in static lead–bismuth eutectic (LBE) have been investigated at 400 °C for 100 h. The results show that the samples without irradiation have many unequal size Fe₃O₄ particles and little Cr-rich oxide after LBE corrosion test, and the thickness of corrosion layer is 4.4 μm. The irradiation samples display plenty compact triangular (Fe,Cr)₃O₄ and some Cr-rich oxide, and the thickness of corrosion layer is 4.4 μm with some cracks. Au-ions irradiation enahnced the LBE corrosion of F/M steel, which could be attributed to the irradiation defects provide diffusion path of O atoms in liquid LBE. A schematic model was presented to understand the effect of irradiation damage on LBE corrosion behavior of F/M steel.

研究了 12Cr2W2Mn 铁素体/马氏体 (F/M) 钢在静态铅铋共晶 (LBE) 中金离子辐照前后的腐蚀特性，在 400 °C 下保持 100 小时。结果表明，未经辐照的样品经LBE腐蚀试验后，有许多不等大小的Fe ₃ O ₄颗粒和少量富铬氧化物，腐蚀层厚度为4.4 μm。辐照样品显示大量紧凑的三角形 (Fe,Cr) ₃ O ₄和一些富铬氧化物，腐蚀层厚度为 4.4 μm，有一些裂纹。Au离子辐照增强了F/M钢的LBE腐蚀，这可能是由于辐照缺陷提供了O原子在液态LBE中的扩散路径。提出了一个示意图模型，以了解辐照损伤对 F/M 钢 LBE 腐蚀行为的影响。
