摘　　要：研究了GH141合金晶界M23C6连续沉淀对合金持久寿命的影响。实验发现，晶界M23C6连续沉淀对持久寿命的降低，可能与热加工温度过高，或变形量较小有关。The effect of continuous precipitation of M23C6 at grain boundary on creep rupture life of GH141 alloy was investigated. It was found that the function of continuous precipitation of M23C6 at grain boundary on lowering creep rupture life might be caused by the bigher hot working temperature or the smaller deformation amount.

关 键 词：高温合金 GH141合金 晶界碳化物沉淀 持久性能
