| Abstract | The effects of P on elemental segregation and as-cast microstructure in Inconel 706 alloy were investigated in this paper. The results showed that P was markedly enriched in residual liquid and enhanced the segregation of Nb and Ti, which promoted the precipitation of Nb-enriched Laves phase and Ti-enriched eta-Ni(3)Ti phase. In the as-cast alloy doped with 0.004% P (mass fraction), fine (Laves+gamma) eutectic and needle like eta phase were formed in interdendritic region. As the P dopant was higher than 0.016%, blocky Laves phase was formed and lath eta particles were precipitated among Laves particles. Moreover, with P increasing from 0.004% to 0.016%, the incipient melting-point was found to drop from 1170-1180 degrees C to 1160-1170 degrees C. In high P-doped alloys, the enrichment of P in the residual liquid was believed to hinder the solidification of gamma phase, as a result, the final solidification temperature was found to be decreased and the solidification was |
