EFFECTS OF ULTRASOUND ON DEFORMATION CHARACTERISTICS OF STRUCTURAL METALS 1 JULY 1963-30 JUNE 1964. PART 1. APPLICATION OF PHOTOELASTICITY,
Abstract
Intense ultrasound having power levels up to 100 w/sq 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)
