Principles of Ultrasonic Metal Processing

High energy ultrasound has special acoustic effects. Introducing ultrasonic vibration during the solidification process of metals, the solidification structure changes from coarse columnar crystals to uniformly fine equiaxed crystals, and the macroscopic and microscopic segregation of metals is improved. It is generally believed that high-energy ultrasound has applications in various fields such as ultrasonic treatment, ultrasonic metal treatment, ultrasonic grain refinement, ultrasonic metal solidification, ultrasonic melt defoaming, ultrasonic crystallization, ultrasonic cavitation, ultrasonic casting, ultrasonic solidification microstructure, and ultrasonic metal continuous casting
