Abstract
The dislocation internal friction dependency on sample crystallographic orientation, ultrasonic vibration amplitude, and plastic predeformation of the samples is studied for CsI single crystals using the composite piezoelectric vibrator method. The dislocations of the main slip system {110} 〈100〉 are shown to give the predominant contribution to the internal friction value determined at room temperature and in the kHz frequency range. The characteristic ranges of stress amplitude corresponding to different internal friction mechanisms are determined. The starting stress determination method making use of voltage-current characteristics of the composite vibrator is described. The starting stress numerical value for the easy slip system {110} 〈100〉 is found. [Russian Text Ignored]
