| Abstract Scope |
Liquid-state processing methods are essential to improve the quality and mechanical behavior of aluminum alloys. Conventional techniques such as rotary or chemical flux degassing for the removal of hydrogen and inclusions, and the addition of chemical modifiers for the refinement of grains and modification of intermetallic morphology often face limitations and challenges with environmental impact and process control. Ultrasonic Treatment (UST) is a novel technology which presents the capability to simultaneously degas, grain refine, and modify phase morphology all in a single step without the need for gases, fluxes, or chemical modifiers. Application of UST in the liquid-state is critical for its viability as a metal processing step prior to casting or production of wrought materials. Multifrequency UST offers significant advantages over the traditional fixed frequency method including an increased treatable volume, uniform treatment, and higher acoustic intensities with lower power input. This study investigates the liquid-state mechanisms of multifrequency UST to optimize treatment via processing parameters to support its adoption in industry. |
