摘要: The effect of phosphorus on the solidification and solute segregation a directionally solidified IN738 Ni-based superalloy was investigated experimentally employing method partially directional subsequent quick quenching. It found that addition widened solidus-liquidus temperature interval alloy. Both P content rate affected morphology solid-liquid interface precipitation phosphides in Phosphorus segregated largely intercellular/interdendritic regions promoted other alloying elements structure.
