采用新工艺方法──熔铸直接接触反应法制取原位ＴｉＣ粒子增强铸造Ａｌ基复合材料．该方法是将Ａｌ－５．６ｗｔ－％Ｓｉ合金升温至７５０℃，再把Ａｌ－４０ｗｔ－％Ｔｉ－１０ｗｔ－％Ｃ粉末压制块压入，使Ｔｉ和Ｃ在Ａｌ－Ｓｉ合金液中直接反应生成直径为０．１－１．０μｍＴｉＣ颗粒，并均匀地分布在α－Ａｌ基体中，晶界上无明显颗粒聚集，制成品性能优异．
A novel technique to make in-situ TiC Particulate in an Al-5.6Wt%Si matrix has been developed through direct-contact reaction.An Al-Ti-C compact is pushed into Al-Si alloy at 750℃. The titanium and carbon react directly to form fine TiC particulates (0.1-1.0μm) in liquid Al-Si alloy.The structures indicate that TiC enters into α-Al matrix during solidification and α-Al matrix is reinforced by the dispersion of TiC particulates. This new way to produce cast metal matrix composites is of great future.
