Abstract:

Intense ultrasound having power levels up to 100 wsq cm at 20 kc is used in studies of mechanisms of metal deformation and treatment. To provide accurate quantitative information about the underlying experimental conditions, Part 1 of this progress report describes detailed investigations of modes of propagation of intense ultrasonic stress waves in rods and bars. Part 2 will be concerned with measurements of conversion of acoustic energy into heat and kinetic energy of lattice imperfections. Parts 3 and 4 will illustrate experiments in which high strain rate tensile tests, and intense pulsed ultrasound were applied. A discussion of ultrasonic metal deformation will be given in the final Part 5 along with a comparison of our observations with results and viewpoints from other reports on this subject. Author
