Fe-9Cr, Fe-9Cr-1Mo and Fe-9Cr-0.5Mo-0.5Ni (wt%) alloys have been prepared for studying the effect of (Mo, Mo/Ni) on carbide precipitation, oxidation behavior and high-temperature tensile property of Fe-9Cr alloy. Rod-shaped Cr₂₃C₆ precipitates in Fe-9Cr alloy were refined and spheroidized by Mo addition, while Mo/Ni addition had no impact on Cr₂₃C₆ precipitates. Adding (Mo, Mo/Ni) to Fe-9Cr alloy reduced inward oxygen diffusion and the growth rate of an inner Cr-rich layer, thereby accelerating chromia formation and improving the oxidation resistance. High-temperature strength of Fe-9Cr alloy was also enhanced by alloying elements (Mo, Mo/Ni).

制备了Fe-9Cr，Fe-9Cr-1Mo和Fe-9Cr-0.5Mo-0.5Ni（wt％）合金以研究（Mo，Mo / Ni）对碳化物沉淀，氧化行为和高温拉伸的影响Fe-9Cr合金的性能 Fe-9Cr合金中的棒状Cr ₂₃ C ₆析出物通过添加Mo进行细化和球化，而添加Mo / Ni对Cr ₂₃ C ₆析出物没有影响。向Fe-9Cr合金中添加（Mo，Mo / Ni）可减少向内的氧扩散和内部富Cr层的生长速率，从而加速氧化铬的形成并提高抗氧化性。Fe-9Cr合金的高温强度还通过添加合金元素（Mo，Mo / Ni）来提高。
