Abstract
An apparatus and method for ultrasonically detecting inclusions in molten metals. The apparatus includes a probe comprising an inert refractory shell, a window supported by the shell for carrying ultrasonic waves between a coupling medium and a body of molten metal, and a coupling medium contained within the shell for carrying ultrasonic waves between a transducer and the window. A preferred apparatus utilizes a coupling medium comprising liquid gallium and is suitable for detecting inclusions in molten aluminum and aluminum alloys.
