Oxide scales were prepared by cooling low-carbon steel wires at different rates and the microstructure was investigated by X-ray diffraction (XRD) and Mossbauer spectroscopy. The distribution of Fe3O4 in the oxide scale was obtained using Magnetic Force Microscope (MFM), through which the influence of the cooling rate on the distribution of Fe3O4 was studied. The results showed that when lowcarbon steel wires are rapidly cooled, the content of Fe2O3 in the oxide scale decreases while the content ratio of FeO to Fe3O4 increases. At the same time, the content of stoichiometric FeO and the defect concentration of Fe3O4 can also change with different cooling rates. The phase composition of the oxide scale and the distribution of Fe3O4 are the main factors that affect the properties of the oxide scale.
