摘要	When phosphorus content is below 0.040%, no obvious effect on the tensile properties of GH761 alloy at room temperature and 650 degrees C was observed. However, phosphorus influenced the stress rupture properties of GH761 alloy greatly. The peak value of the rupture life at 650 degrees C and 637 MPa appeared at 0.023% phosphorus. At the point, the life was longer than 970 h, more than 3 times of that when the phosphorus content is 0.0007%. Phosphorus can prolong the rupture life of GH761 alloy by inhibiting the dislocation glide, increasing the intergranular precipitation and blocking the diffusion of oxygen along gain boundaries. However, excessive addition of phosphorus lowered the grain boundary strength by deteriorating the grain boundary precipitation and causing the precipitation of eta-Ni3Ti, which shortened the rupture life of GH761 alloy.
