Effect of Annealing Atmosphere and Steel Alloy Composition on Oxide Formation and Radiative Properties of Advanced High-Strength Steel Strip

This study elucidates the effect of alloy composition, annealing atmosphere, and pre-annealed surface state on the radiative properties of dual-phase (DP) steels. Twelve samples of varying alloy composition and pre-annealed surface roughness were heated in a 95 pct/5 pct (vol) N2/H2 process atmosphere under dew points of + 10 °C and − 30 °C. The surface profile and surface topography were characterized using scanning electron microscopy and …
