本文采用高能超声波搅拌法制备半固态Al-Si合金，研究不同材料的超声波振动头对半固态微观凝固组织的影响以及超声波振动时间对半固态微观凝固组织的影响。
实验中使用了4个超声波振动头，除钛合金振动头外，还有1个45号钢平顶振动头，1个45钢球状顶振动头，1个镍合金钢振动头。在Al-Si合金液固相线温度区内，用上述4个振动头分别伸入浆料中振动1m，在0.3m，0.5m，0.8m，1.0m时用石英管抽样。再在显微镜下观察微观组织。
实验结果表明，4个振动头都能够在一定程度上使组织细化，晶粒变得更加圆整。但相比之下，钛合金振动头的细化效果最好，其他3个振动的效果与之相比都还有一些差距。45号钢球状顶振动头更加接近钛合金振动头的效果，在某些要求不高的情况下可以代替钛合金振动头。

Preparation of high-energy ultrasound semi-solid metal slurry used ultrasonic vibration of the first manufacturers in general by the titanium alloy, and titanium alloy materials are very expensive, making the cost too high to be practical to use large-scale production. The purpose of this study is trying to find a cheap metal materials to replace expensive titanium alloy material, to substantially reduce costs in order to facilitate the actual production of the technology in the promotion.
In this paper, prepared by high-energy ultrasonic stirring semi-solid Al-Si alloys, of different materials, the first of ultrasonic vibration micro-solidification structure of semi-solid and ultrasonic vibration of the impact of time on the micro-solidification structure of semi-solid impact.
Experiment using the first four ultrasonic vibration, with the exception of titanium head vibration, there is a vibration of 45 steel flat-topped head, a vibration of the top 45 steel sph
