) extends the ultrasonic vibration time which makes some of the primary α-Mg particles grow larger, and high cooling rate (8.04 ℃/min) improves the particle growth rate which also makes the particles larger. In summary, the cooling rate during ultrasonic vibration could not be too high or too low, and the appropriate cooling rate in the experimental conditions of this study is 2-3 ℃/min. ......
