摘　　要：探讨了稀土－钡－磷复合变质剂对ＺＬ１０８合金组织和性能的影响。试验结果表明，合金中加入该变质剂，不仅获得完全的变质组织，而且变质效果稳定，其长效性和重熔性较好。简要探讨了该变质剂的变质机理。The effect of RE Ba P composite modifier on the structure and properties of ZL108 alloy has been investigated.The results showed that,when the modifier is added to the alloy,both the complete modified structure and the steady modifiying effect can be obtained,the ability of long life modification and remelting are better,the modifiying mechanism using the composite modifier was also discussed briefly.
