It was found in investigating of the structural states in austenitic Fe alloys with 19% Ni and 10% Ru; 27% Ni and 2% Ru, and in an 34.4% Ni with FCC lattices that particles of a solid Fe-Ru solution in NiO form in the course of electrical polishing. No such particles were observed in a Fe alloy with 20% Ni, which has an α phase structure with a BCC lattice. The formation of the(Fe, Ru, Ni)0 particles is attributed to penetration of oxygen atoms into the austenite lattice.
