Broad prospects for commercial application of the ultrasonic (cavitation) melt treatment of light alloys

Theoretical and applied aspects of ultrasonic melt treatment are considered. Industrial applications of the cavitation treatment for degassing, filtration, and grain refinement are illustrated using data for commercial alloys. Some new fields of use such as semisolid processing, low-friction alloys, and natural composites are discussed. In general, wide prospects of commercial application for the ultrasonic melt treatment of light alloys are shown. (C) 2001 Elsevier Science B.V. AU rights reserved.
