摘要：

The effect of P content on micro-segregation in Incoloy 903 alloy was investigated by using electron microprobe analysis and TEM/EDS. It was found that by lowering the P (Mn) content in the alloy, the equilibrium partition coefficients of Nb and Ti increased, solidification micro-segregation of Nb and Ti lowered and formation of the Laves phase was eliminated.
