摘　　要：研究了磷和硼对 Ｉｎｃｏｎｅｌ ７１８ 合金持久和蠕变性能的影响。结果表明， 单独添加 ００２％ 磷对性能明显有益， 单独提高硼含量至 ００１％ 对性能有害， 复合添加磷和硼的效果最佳。磷和硼复合作用显著有益的原因在于磷与硼之间存在强烈有益的交互作用， 其机制可能与磷、硼和基体原子的晶界集团扩散有关。The effect of phosphorus and boron on stress rupture and creep properties of Inconel 718 alloy has been studied The results indicate that addition of 0 02% phosphorus alone is beneficial and increasing boron content alone to 0 01% is harmful The optimum property improvements can be achieved by combined addition of phosphorus and boron due to the strong beneficial interaction between phosphorus and boron, which probably associates with the group grain boundary diffusion of phosphorus, boron, and matrix atoms

关 键 词：磷-硼交互作用 持久寿命 蠕变速率 高温合金
