论文摘要
在低纯度（F-M钢的模型合金）的Fe-Cr合金辐照后，已证明像P，Ni和Si一样较小的溶质元素会产生溶质簇，从而有助于硬化，并可能与小错位环相关。为了了解每种杂质在辐照下形成的纳米特征的作用，以及不同物种之间的最终协同作用，Fe-15at。％Cr-X（X = Si，Ni，ni，p，nisip，Nisip），具有不同组合物的合金，并使用ATOM探针进行了离子辐照和表征。在300 {\ textDegree} c上进行辐照，四种合金中的2.5 dpa：fe15crni，fe15crsi，fe15crp和fe15crnisip。还讨论了在辐照过程中植入的C原子对纳米结构进化的影响。对在辐照下形成的纳米辅助的演变的研究突出了P和C在形成纳米群体中的作用，并确认了富含溶质的簇的辐射性质。
After irradiation of Fe-Cr alloys of low purity (model alloys of F-M steels), minor solute elements as P, Ni and Si have been shown to create solute clusters which significantly contribute to hardening and might be associated with small dislocation loops. In order to understand the role of each impurity on the formation of the nano-features formed under irradiation and the eventual synergies between the different species, Fe-15at.%Cr-X (X=Si, Ni, P, NiSiP) alloys of different composition have been ion irradiated and characterized using atom probe tomography. Irradiation were performed at 300 {\textdegree}C up to 2.5 dpa in four alloys: Fe15CrNi, Fe15CrSi, Fe15CrP and Fe15CrNiSiP. Influence of C atoms implanted during irradiation on the nanostructure evolution is also discussed. The study of the evolution of the nanofeatures formed under irradiation with the dose as a function of the composition highlights the role of P and C on the formation of the nano-clusters and confirm the radiation-induced nature of solute-rich clusters.
