Abstract:
The selective oxidation process of dual‐phase 1180 steel was investigated in this study. Annealing was carried out in Cr/Cr 2 O 3 Rhines pack at 820°C for 60, 120, and 240 s, under the oxygen partial pressures of 10 −23 , 10 −25 , and 10 −29 atm, respectively. Field emission scanning electron microscopy (FE‐SEM), electron backscattered diffraction (EBSD), and X‐ray photoelectron spectroscopy (XPS) were used to analyze the experimental results. The oxides involved SiO 2 , MnO, MnSiO 3 , Mn 2 SiO 4 , and MnCr 2 O 4 . The amount of oxides augmented along with the increasing oxygen partial pressure. The Fe–Mn–Cr–Si–C–O 2 oxidation diagram was calculated by thermodynamic software and was used to explain the selective oxidation process of dual‐phase 1180 steel. Experimental results combined with the thermodynamic computations well.
