Abstract:
Existing technological synthesis capabilities let you receive samples of macroscopic size only for a limited number of single-quasicrystalls. However, the traditional applications of single crystals in the functional electronics (for example, multiple acoustic wave sensors) may be actual for single-quasicrystalls. The main criteria for such applications of single-quasicrystalls are macroscopic material constants and characteristics of acoustic waves with propagation in them.
In this work, pulsed ultrasonic method in macroscopic samples single-quasicrystalls Ag42In42Yb16 with linear dimensions about 1 cm investigated characteristics of acoustic waves' propagation. The elastic constants are analyzed in the isotropic and cubic approximations on the basis of the experimentally determined values of the bulk acoustic waves' velocities. The attenuation coefficients of longitudinal and shear acoustic modes for different directions of propagation determined by attenuation of the reflected pulses series.
