Ultrasonic In-situ Monitoring of Aluminum Alloy during Solidification and Melting

In situ ultrasonic interface tracking for photovoltaic silicon directional solidification

“…This method has demonstrated its interest in several configurations considering metallic alloys. In Al-based alloys, for example, ultrasounds are used for interface tracking [13,14], but also particle detection [15], acoustic velocimetry [16,17] and action on the process through acoustic streaming and cavitation [18,19,20]. A recurring issue is to define whether the waveguide has to be water-cooled.…”
