| 摘 要： | 镍基单晶高温合金因其优异的高温力学性能、抗热腐蚀性能成为航空发动机中不可替代的涡轮叶片材料,少量稀有元素铼(Re)能大幅提高镍基高温合金的承温能力和力学性能,这一现象被称为"铼效应"。近几十年来,铼效应的强化机理备受关注,简要综述了国内外关于铼元素在高温合金中分布特征的研究进展及对应的铼强化机理,并展望了镍基高温合金中铼效应的研究趋势及挑战。

| Abstract: | Nickel based single crystalline superalloys are irreplaceable materials for blades of aero-engines due to their superior mechanical properties and corrosion resistance at high temperature.A small amount of rhenium(Re)can significantly improve both temperature capability and mechanical properties of nickel superalloys which is referred to as"Re effect".This paper briefly reviews research progresses on the distribution of Re in nickel superalloys,and the corresponding strengthening mechanisms.A discussion on the future researches and challenges on the study of"rhenium effect"are prospected. |
