Abstract: | The effects of P and B on the creep behavior of 718 alloys are discussed in this paper. The result implies that P and B have little effect on the γ″ and γ′ phases of the alloy, but they can enhance the grain boundary strength by segregating there, which can be of beneficial to the higher creep properties. P also may increase the grains strength through solid solution. The beneficial effect of P and B were presented in both standard IN718 alloy and DA718 alloy. Adding P and B together does a better work than adding P alone. |
