摘要
综述了国内外单晶高温合金蠕变行为研究现状,分析了蠕变行为中γ′相定向粗化机理、蠕变各向异性和蠕变过程中位错演化问题,探讨了单晶高温合金蠕变行为的研究方向。
The present situation of research on creep behavior of the single crystal superalloys was reviewed. The mechanism of directional coarsening of γ, the creep anisotropy and the dislocation evolution during creep were analyzed and the study direction of creep behavior of the single crystal superalloys was approached.
