 note = {By means of microscopic observation, thermo-magnetic, dilatometric and X-ray analyses, as well as measurements of specific heat and electric resistance at elevated temperatures, hardness, electric resistance and intensity of magnetization at room temperature, etc., the formations of superlattices as well as of compound in Fe-Cr system were systematically investigated. And it was discovered that there are formed three metastable ferromagnetic superlattices, Fe3Cr(α’3-1), FeCr (α’1-1）and FeCr3 (α’1-3), and also two meta-compounds, Fe2Cr (τ-phase) and FeCr2 (ω-phase), besides the well-known stable nonmagnetic compound, σ-phase. σ-phase is formed from disordered α solid solution at higher temperatures near 800°. Whlie, superlattice α’1-1 can be formed for once from the supercooled α-phase at lower temperatures near 500° by prolonged annealing, but finally transforms into σ-phase by further annealing. From these results, it was concluded that the superlattice FeCr (α’1-1) is a metastable and intermediate phase between the disordered solid solution α and the stable compound σ.},
