Abstract
The strengthening effect of phosphorus and boron on wrought superalloys is reviewed and discussed. The addition of phosphorus and boron can prolong the rupture life of some wrought superalloys over 3 times, and lowers the constant creep rate by an order of magnitude. By micro-alloying with phosphorus and boron, alloys with extended rupture life are developed, the service temperature of IN718 alloy is enhanced, and the alloys which can be used for a long time at 700℃ with higher combined properties can be developed.
