Controlling and predicting the product quality in casting is important but difficult because of the opacity and the complicated properties of molten metal, as well as its complex flow during solidification. Our research aims to enable real-time imaging and flow measurement via ultrasound metrology in liquid metal during solidification. The experiments described here focus on low melting-temperature metal Gallium and its alloys, which allow controlling oxygen and oxide content precisely. By designing and building a novel experimental setup that allows for precise control of temperature and chemical composition, we investigated the mechanisms of interaction among ultrasound, metal oxide, and oxygen. The ultrasonic measurement results and microscale characterization presented here can be used to develop kinetic models for dissolved oxygen and oxide inclusions in liquid metal in the future.
