Application of Ultrasonic on Metal Matrix Composites Prepared by Casting Method
Application status of high-octane ultrasonic on preparation of casting metal matrix composites has been summarized. It plays an important role to purification of alloy, pretreatment’s aggrandizement,improvement of wet-ability, surface combination, equality distribution of increased phase and preparation techniques’ stabilization. The study directions for researcher of material are as follow: first of all, selecting the frequency, intensity, time of ultrasonic to optimize compound technology parameter Secondly, discussing on mechanism of ultrasonic driving grain and ultrasonic composite Thiredly, consummating ultrasonic (equipments.)
