中文摘要：

一个电致伸缩的单轴的超声的悬浮反应系统被设计由在 Al-3Ti 推迟石墨粉末执行 TiC 合成反应融化并且 Al-3Ti-0.15C 谷物更精制的合金被获得。在哪个石墨推迟的健全压力节点在在放射块之间的 melt 被形成并且思考的结果表演登机由超声并且 TiAl ₃ 粒子同时在 C 粉末附近集合由于超声的成穴，溶解了 TiAl ₃ 更好为 TiC 的合成反应提供表面状况。反应线路是 C 和溶解 Ti 反应形成 TiC。超声的成穴在 TiC 粒子和 Al-3Ti-0.15C 上有热激活效果更精制有优秀微结构在 α-Al 上精制效果。

英文摘要：

An electrostrictive uniaxial ultrasonic levitation reaction system was designed to perform TiC synthesis reaction by suspending graphite powder in Al-3Ti melt and an Al-3Ti-0.15C grain refiner alloy was obtained. The results show that sound pressure node in which graphite suspends is formed in the melt between radiation block and reflecting board by ultrasonic and TiAl3 particles congregate around C powder. Meanwhile, due to ultrasonic cavitation, dissolved TiAl3 provides better surface condition for the synthesis reaction of TiC. The reaction route is that C and dissolved Ti react to form TiC. Ultrasonic cavitation has a thermal activation effect on TiC particles and Al-3Ti-0.15C refiner has excellent microstructural refining effect on α-Al.
