摘要
用Ｋ２ＴｉＦ６、ＫＢＦ４、ＲＥ分别或对ＺＡ２７合金变质处理。试验表明：在砂铸情况下，用Ｋ２ＴｉＦ６、ＫＢＦ４、ＲＥ进行变质处理是提高ＺＡ２７合金塑韧性的有效方法，其中以Ｋ２ＴｉＦ６＋ＫＢＦ４的效果最好。此外，对变质处理细化晶粒的机理进行了研究，研究表明：ＴｉＡｌ３、ＡｌＢ２、ＡｌＣｅ、Ａｌ２Ｃｅ等可作为α相生核的衬底，显著细化α相。
The modification of alloy ZA27 using K 2TiF 6 KBF 4 and RE has been investigated,The experiment results obtained shows that the way is efficience for enchancing the ductility of alloy ZA27 under the condition of sand casting,and the effect of modification for alloy ZA27 using K 2TiF 6+KBF 4 is comparatively good The mechanisms of grain refinement in the alloy have been also studied TiAl 3 AlB 2 AlCe and Al 2Ce can be used as the crystal ling for α phase which will refine α phase remarkbly
