摘　　要：独特的γ'相使镍基高温合金具有良好的疲劳和蠕变性能,在航空航天和高参数发电等领域具有广阔的应用前景。从γ'相的尺寸、含量和位错强化方面介绍了γ'相对镍基高温合金强化行为的影响以及位错与析出相交互作用的剪切、Orowan绕过和攀移等强化机制,阐述了γ'相对镍基高温合金疲劳和蠕变性能的影响。最后,对镍基高温合金中γ'相的优化及相关性能调控进行了展望。Nickel-based superalloys have good fatigue and creep properties due to their uniqueγ'phase,and have wide application in aerospace and high-parameter power generation industries.The effect ofγ'phase on the strengthening behavior of nickel-based superalloys from aspects of size and content ofγ'phase and dislocation strengthening,and the strengthening mechanisms of interaction between dislocations and precipitates,including shear,Orowan bypass and climb,are described.The influence ofγ'phase on fatigue and creep properties of nickelbased superalloys is discussed.Finally,the optimization ofγ'phase and associated performance control of nickelbased superalloys are prospected.
