摘要 AMOLDMATERIALUSEDFORTITANIUMALUMINUMALLOY—CALCIA①GuoJingjie,SuYanqing,LiuYuan,DingHongsheng,RenZhijiangandJiaJunSchoolofMate... The effects of binder, additive and sintering temperature on the properties of calcia as a mold material used for titaniumaluminum alloys have been studied. The results showed that the solution of CaCl2C2H5OH is the best binder for calcia, the additive of CaF2 not only increases the strength but also the antiwatering property of calcia; sintering at 900~1 000 ℃is adaptable. The contamination of calcia on titaniumaluminum alloy castings has been studied, and the experimental results showed that the thickness of contamination is less than 15 μm.
