Book Description
On June 21 a symposium was sponsored by the Bureau of Naval Weapons on the application of ultrasonic energy in the deformation of metals. At this session, a number of investigators actively working in the field reported informally on the results of their research. The reports revealed that the results achieved by incorporating ultrasonic transducers into conventional metalforming and-cutting operations are sufficiently promising that the technique merits further attention. Data are available to indicate that application of ultrasonic vibrations during metal working can increase speeds, lower forces, and improve surface finishes. All of these results have been obtained without any observed difference in properties between ultrasonically and conventionally fabricated parts. (Author).

Book Description
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).

Book Description
High-intensity ultrasound at 20 kc/sec is used in studies of mechanisms of metal deformation and treatment. Quantitative details about the experimental conditions are provided in 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.

Book Description
Mechanical vibrations of ultrasonic frequency exert a considerable influence upon the mechanical properties of metals, in particular, their deformation characteristics. The following three phenomena are considered: ultrasonic softening, ultrasonic hardening and the influence of preliminary ultrasonic treatment upon the steady-state creep of metals. Ultrasonic softening takes place when a ultrasonic loading is superimposed upon a static one, which results in the decrease of static load needed to deform the metal. Ultrasonic hardening occurs during the sonication of annealed material without a static loading. The ultrasonic hardening manifests itself in the increase of the yield strength of material due to the defects of crystalline structure nucleated and developed in acoustic field. Ultrasonic treatment consists of the ultrasonic irradiation of material and subsequent annealing. Materials treated in such a way can offer a considerable resistance to creep deformation. However, this tendency is not a monotonic function of the preliminary sonification parameters. A new theory, the synthetic theory of irrecoverable deformation, is employed to model the phenomena discussed above.
