| Abstract | Effect of segregation behaviors of P at different cooling rates on the precipitation of gamma '' and gamma' phases and the corresponding strength are investigated. The precipitation of gamma '' and gamma' phases during cooling is sensitive to P concentration. With increasing the concentration of P, the amount of gamma '' and gamma' particles increases after air cooling. With decreasing the cooling rate, the accelerating effect of P on the precipitation of gamma '' and gamma' phases decreased first and then increased, which demonstrates the concentration of P dissolved in the grain interior decreases first and then increases. The different effects of P on gamma '' and gamma' phases with different cooling rates were analyzed by the kinetic characteristic of nonequilibrium grain-boundary segregation. The characteristic of nonequilibrium grain-boundary segregation of P in superalloy is further confirmed, and the phenomenon caused by critical cooling rate is captured.
