摘　　要：研究了磷对IN718合金δ相的影响，结果表明，磷改善热处理态组织中δ相的形态和分布，显著抑制时效过程中δ相的生长．The influence of phosphorus on 6-phase in IN718 alloy has been studied. The results showthat phosphorus improves both the morphology and distribution of b-phase in as-heat-treated samplesand markedly inhibits b growth during aging. The inhibiting on b growth probably associates with thesuppressing effect of phosphorus on diffusion.
