Abstract:
The effect of ultrasonic deformation on the inelastic behavior of potassium hydrogen phthalate single-crystal samples with different crystallographic orientations at frequencies of $\sim$10$^5$ Hz has been investigated. It has been shown that the inelastic behavior of potassium hydrogen phthalate single crystals during the ultrasonic deformation is determined not by the dislocation mechanisms. It has been found that the main mechanism responsible for energy losses of mechanical vibrations in these crystals is the mechanism of ionicrelaxation polarization. The characteristic relaxation times of this process have been determined and varied in the range from 10$^{-8}$ to 10$^{-7}$ s.
