Ultrasonic processing of aluminum alloys

The research in ultrasonic processing for metallurgical application shows a promising influence on improving casting properties of aluminium alloys. The principle of ultrasonic processing is introduction of acoustic waves with a frequency higher than 17 kHz into liquid metal. Several promising beneficial effects caused by ultrasonic processing in aluminium alloys were observed and researched, such as ultrasonic-aided grain refinement, reduction of thermal contraction during solidification, and ultrasonic degassing. The systematic study of this subject allows us to achieve a better understanding of ultrasonic processing in aluminium alloys. It also provides valuable information for optimization of ultrasonic processing parameters in industrial application.MSEMechanical, Maritime and Materials Engineerin
