%X 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 finegrained 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℃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 10west in a11 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 GH761 alloy can be improved by grain refining and appropriate amount of P addition.
