Normal Spectral Emissivities of Liquid Iron, Liquid Nickel, and Liquid Iron-Nickel Alloys

摘要

The normal spectral emissivities of liquid iron, liquid nickel, and liquid iron-nickel alloys over the complete range of composition were determined at wavelength lambda = 645 nm by an integral blackbody comparison method. The emissivities of constant from 1809 to 1857 exp 0 K for liquid iron, from 1729 to 1823 exp 0 K for liquid nickel, and from 1810 to 1890 exp 0 K for liquid iron-nickel alloys. The normal spectral emissivity of liquid iron-nickel alloy is dependent on composition. (ERA citation 06:018960)
