采用普通机械搅拌熔铸法和逆向熔铸法（先熔中间合金后加基体材料）对原位反应合成法（即XD法）制备TiC／2618复合材料的工艺过程进行了研究．结果表明：逆向熔铸法可增加中间合金的可熔性，有效减少了熔铸过程中TiC粒子的损失，制得较为理想的复合材料．图4，参4 The process of preparing TiC / 2618 composite by in-situ reaction synthesis (ie XD method) was studied by using ordinary mechanical stirring casting method and reverse casting method (first melting master alloy followed by matrix material). The results show that the reverse casting method can increase the fusibility of the master alloy and effectively reduce the loss of TiC particles during the casting process, resulting in an ideal composite material.
