Relation between emissivity evolution during annealing and selective oxidation of TRIP steel

Abstract : Spectral emissivity measurement (λ = 8–12 μm) of TRIP alloy steel during annealing in HNx atmosphere is carried out. Emissivity variation is contributed by the selective oxidation that takes place along with the surface topography from pre-annealed state. Comparing results from physicochemical characterization (Fourier transform infrared spectroscopy, scanning electron microscopy and optical surface profiler) on post-annealed samples and examining the global and relative spectral emissivity separately established correlation of roughness to the former and oxide signatures to the peak features in the latter. Intensity of emissivity peaks at 10 μm and 10.5 μm vary with ratio of Mn to Al. Meanwhile, the influence of local texture on emissivity is demonstrated.
