摘　　要：目的:比较3种不同包埋材料对医用Ti-6Al-7Nb合金铸流率的影响。方法:采用网状试样法,以纯钛为对照,分别对3种不同体系包埋材料(氧化镁系、磷酸盐系、氧化锆系)铸出的Ti-6Al-7Nb合金试件的铸流率进行评价。结果:各组试件铸流率均达到90%以上,3种包埋料包埋的铸件铸流率无明显差异(P>0.05),纯钛组和Ti-6Al-7Nb组间也无显著性差异(P>0.05)。结论:Ti-6Al-7Nb合金与纯钛一样具有较高的铸流率,且受3种包埋料的影响均较小。Objective： To evaluate the influence of three investments on the castability of Ti-6A1-7Nb alloy. Method： Net patterns were applied in this study. Pure titanium and Ti-6A1-7Nb alloy were invested in three investments respectively including MgO,Phosphate, and ZrO2 series investment. The castability value was obtained by counting the complete segment of the cast alloy grid. Result： Various investments had no significant influence on the castability of the two alloys. And also, there had no significant difference between pure titanium and Ti-6A1-7Nb （P〉0.05） in their castability, both were over 90%. Conclusion： pure titanium and Ti-6A1-7Nb alloy had excellent castability. The three.investments had no significant effect on the castability of the two alloys.
