High-Frequency Vibration and Ultrasonic Processing

Abstract

The application of ultrasound to the processing of liquids and slurries has a long history. This chapter considers the main mechanisms of ultrasonic processing of metallic alloys as well as principal applications of this technology to processing of liquid metals, casting of alloys and manufacturing of new materials. Some theoretical background is given as well, The text is illustrated with historical and new results including those obtained with most advanced techniques such as high-temperature cavitometry, high-speed in-situ observations and X-ray synchrotron imaging.
