Abstract Spectral emissivity measurement (λ = 8–12 μm) of TRIP alloy steel during annealing in HN x 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.

TRIP钢退火与选择氧化过程中发射率演变的关系

摘要 对TRIP合金钢在HN x 气氛中退火过程中的光谱发射率（λ = 8-12 μm）进行了测量。发射率变化是由与预退火状态的表面形貌一起发生的选择性氧化造成的。比较后退火样品的物理化学表征（傅里叶变换红外光谱、扫描电子显微镜和光学表面轮廓仪）的结果，并分别检查全局和相对光谱发射率，分别确定粗糙度与前者和氧化物特征与后者峰值特征的相关性. 10 μm 和 10.5 μm 处的发射率峰值强度随 Mn 与 Al 的比率而变化。同时，证明了局部纹理对发射率的影响。
