摘要：
In-situ blocky Al3Ti particles can be synthesized by direct reaction between solid Ti powders and liquid Al in terms of reaction-peeling model. In this research, the effect of high-intensity ultrasonic vibration on the reaction was investigated by means of immersing the ultrasonic radiator in the Al melt at 1003 K (730 degrees C) during the fabricating process. The results show that the thickness of Al3Ti reaction layers can be decreased to range from 2 to 3 mu m, and the sizes of most of Al3Ti particles can be reduced in the ultrasonic fields as well, with the average size ranging from 2 to 3 mu m. The two changes are both attributed to the effects of external forces produced in the ultrasonic fields. Thereby, small blocky Al3Ti particles can be peeled off from the reaction layer more quickly, making reaction layers to become thinner and the particles smaller.
