Abstract
Results of measurements made during high-power ultrasonic insonation of metal specimens give new insight into the mechanical and thermal processes involved. Changes observed in the ultrasonic attenuation of test specimens during insonation indicate that high-power ultrasound can create and/or move dislocations. Measurements of the ultrasonic velocity indicate change in the moduli of the material during insonation. Heating of the test specimen to various degrees, depending upon both the specimen configuration and material has also been observed during high-power ultrasonic insonation. Details of these and further results are discussed.
