Abstract:

High-intensity ultrasound at 20 kcsec is used in studies of mechanisms metal deformation and treatment. Quantitative details ab6ut the experimental conditions are providedin the five parts of this report 1 modes of intense ultrasonic stress waves in rods and bars, 2 conversion of acoustic energy into heat, 3 applications of ultrasound at high-strain-rate tensile tests, 4 measurements of internal friction during high-intensity ultrasonic radiation of metals, and 5 discussion of ultrasonic metal deformation along with a comparison between our observations and other reports on the subject of ultrasonic metal forming processes.
