| 英文摘要 | Effect of P content on the microstructure and mechanical properties of fine-grained GH761 alloy was studied. The results showed that no obvious effect on the tensile properties of fine-grained GH761 alloy was observed when P content in GH761 alloy was below 0.040% (mass fraction). However, P influenced the stress rupture and creep properties greatly. The peak value of the life at 650 degrees C and 690 MPa appeared around 0.023%P. In comparison with that of the alloy with 0.0007%P, the life increased more than 2 times. At the same time, the creep rate of the alloy with 0.023%P is also the lowest in all of alloys. P is beneficial to the mechanical properties of fine-grained GH761 alloy by improving the precipitation at grain boundaries and impeding the disclocation movement. The overall properties of CH761 alloy can be improved by grain refining and appropriate amount of P addition. |
