用重量法和红外光谱研究了含0.004-0.1%Mn的3%Sisingle键Fe合金在850℃不同的H_2O-H_2气氛中的氧化行为。当气氛中的氧势(H_2O/H_2比)为-0.5时，少量的Mn对3%S_2O键Fe合金的氧化行为(氧化速率和氧化产物)没有影响。当环境气氛中H_2O/H_2时，用电子衍射仪、IMMA和EPMA检测到了(Fe，Mn)_2SiO_4和(Fe，Mn)SiO_3。少量的锰促进了氧化。
Gravimetric and infrared spectroscopic studies on the oxidation of 3%Sisingle bondFe alloys containing 0.004–0.1%Mn were made in various H2O-H2atmospheres at 850°C. When the oxygen potential (H2O/H2ratio) of the ambient atmosphere was > 0.5, small amounts of Mn gave no effect on the oxidation behaviour (oxidation rate and oxidation products) of the 3%Sisingle bondFe alloy. When the H2O/H2ratio of the ambient atmosphere was < 0.3, (Fe,Mn)2SiO4and (Fe,Mn)SiO3were detected in the outermost layer of the subscale by means of electron diffraction, IMMA and EPMA. Small amounts of Mn accelerated oxidation.
