The effect of ⁵⁷Fe ion implantation on the structure of Nb-Zr alloy has been studied using Mössbauer spectroscopy and X-ray diffraction techniques. The ⁵⁷Fe ion beam had an energy of 0.2 MeV and a fluence of 1 × 10¹⁷ ions/cm². The average concentration of implanted Fe ions was ~ 16 at%; the average displacement per atom (dpa) was ~ 438. As a result of implantation a metastable structure was formed in the Nb-Zr alloy. Mössbauer spectroscopy identified three distinct iron states. A singlet indicated a supersaturated solid solution Nb(Fe); two doublets characterized the diffusion migration of atomic planes and crystallization of voids. Studies of the alloy after implantation revealed the formation of a layered structure. The results showed that the surface layer up to 100 nm thick consisted of a mixture of the intermetallic compound Fe₂Nb and a solid solution of Nb(Fe) with a maximum Fe solubility of 0.1 at%. X-ray analysis indicated that the main part of the sample consisted of a solid solution of Nb(Zr).
