Abstract
The development of ultrasonic techniques for imaging and measurements in molten aluminum (Al) using clad buffer rods operated at 10 MHz is presented. The ultrasonic image of a character "N", engraved on a stainless steel plate immersed in molten Al, has been observed at 780/spl deg/C using the focused probe. Inclusion detection experiments have been conducted in reflection configurations involving pitch-catch and pulse-echo modes. The backscattered ultrasonic signals from the silicon carbide particles with an averaged diameter of 50 /spl mu/m suspended in molten Al are successfully detected due to the high signal-to-noise ratio of the clad buffer rods.
