摘要
氧化物弥散强化商业高温合金因氧化物颗粒在基体中的弥散强化作用而具有较好的高温力学性能,如今被广泛应用于航空航天、能源、汽车等领域的高温部件。研究发现,氧化物颗粒的掺杂不仅可以使合金基体具有优异的高温强度,还可以显著提高基体的抗氧化性能。概述了氧化物颗粒种类、尺寸和含量对高温合金抗氧化性能的影响,从合金初期氧化行为、氧化膜生长速度、生长机制、粘附性能等角度重点关注不同性质氧化物(如活性元素氧化物和非活性元素氧化物)弥散质点在氧化过程中作用机理的异同,最后对未来的研究方向做出了展望。
Oxide dispersion strengthened（ ODS） commercial superalloys,with fine high temperature mechanical properties because of the oxide dispersion strengthening effect,are widely developed and applied on the high temperature components of various fields,such as aviation,aerospace,energy,automobile and so on. It is found that the fine oxide particles could effectively improve not only the strength,but also the high temperature oxidation resistance of alloy. The effects of different kinds of oxides,oxide size and oxide content on the high temperature oxidation resistance of superalloys are provided herein on recent advances,focusing on the similarities and differences in the oxidation mechanism of various oxides（ i. e. reactive element oxides and inactive element oxides） from the aspect of the initial oxidation,the oxidation kinetics,the oxide scale growth mechanism and adhesion. Finally,the issues that warrant further studies are proposed.
