Аннотация: The pulse - phase method for examination of ultrasonic waves propagation In materials, including mediums with high attenuation of a sound was designed. By automation methods of measurings the opportunity of determination the elastic waves velocities with an frequency range 100 kHz - 30 MHz with the resolution on frequency of 10(-6) Hz is implemented. The phase method and a method of the frequency strobing for recording impulses are realized. These methods allow to define with precision not worse than 10(-9) second the time of ultrasonic waves propagation. Requirements to the minimum linear dimensions of samples are restricted by the method sensitivity only. Velocities of elastic waves and their signal attenuation in ceramic and composites are measured.
