| 摘 要： | 采用物理化学相分析、X射线衍射、金相检验和持久试验等分析方法研究了烟汽轮机叶片合金（GH864）在不同超温试验条件下显微组织中的碳化物含量与持久强度的关系。结果表明：随着GH864合金中碳化物含量的增加，尤其是M23C6量的增多，其持久强度下降，从而缩短了其剩余寿命。

| Abstract: | Relationship between the carbide content in microstructure and the creep rupture strength of GH864 alloy was studied under different overheated condition by using physical and chemical analysis,X-ray diffraction,metallographic examination and creep rupture strength test.The result showed that with the carbide content increase,especially with M23C6 content increase,the creep rupture strength and remaining life of GH864 alloy decreased. |

| Keywords: | GH864 alloy overheated temperature carbide content creep rupture strength remaining life |
