Summary.
Normal spectral emissivity at 684.5 nm of the liquid binary system Fe–Ni was measured by means of a fast ohmic pulse heating technique combined with fast ellipsometry. The experimental values observed of all liquid alloys are dependent on composition and temperature in the entire range of mixing. Spectral emissivity was measured for pure iron, Fe90Ni10, Fe80Ni20, Fe64Ni36, Fe50Ni50, Fe40Ni60, Fe30Ni70, Fe20Ni80, and pure nickel. Emissivity data as a function of temperature (at melting and in the liquid phase up to 2300 K) and as a function of the mixing ratio are presented and compared to the few existing literature-values.
