Abstract

The effect of the implantation of ⁵⁷Fe ions with an energy of 1 MeV and fluence of 5 × 10¹⁶ ion/cm² on the properties of structural materials used in the nuclear industry (metallic Ta and Mo and 12Cr18N10T stainless steel) is studied using ⁵⁷Fe Mössbauer spectroscopy and X-ray diffraction. The concentration of implanted Fe atoms is calculated using the SRIM program. The formation of two phases is found in Ta and Mo. The main phase in molybdenum (84%) is a solid solution of Fe substitution in Mo. The main phase in tantalum (78%) corresponds to Fe-cluster formation in a Ta matrix. Apparently, additional surface phases are related to the formation of Fe + Ta/Mo + vacancy clusters in the areas of grain boundaries, or are associated with areas of partial amorphization of the material.

Mössbauer研究将Fe-57离子注入金属Ta，Mo和不锈钢中的过程

摘要

研究了使用1 MeV能量和5×10 ¹⁶ ion / cm ^2的注量注入⁵⁷ Fe离子对核工业所用结构材料（金属Ta和Mo和12Cr18N10T不锈钢）的性能的影响。⁵⁷FeMössbauer光谱学和X射线衍射。使用SRIM程序计算注入的Fe原子的浓度。在Ta和Mo中发现了两相的形成。钼中的主相（84％）是Mo中Fe的固溶体。钽中的主相（78％）对应于Ta基体中的Fe团簇形成。显然，额外的表面相与在晶界区域中Fe + Ta / Mo +空位簇的形成有关，或与材料的部分非晶化区域有关。
