Samples of rod stock in the form of cylinders made from steel grades 38KhGM and 05Kh16 with real internal defects were investigated. For measurements, an experimental setup was used featuring a specialized through-type EMA transducer for transverse waves with axial polarization at a working frequency of 2.5 MHz, as well as an ultrasonic flaw detector DIO-1000 PA equipped with a piezoelectric converter for longitudinal waves based on flexible PVDF piezo film installed circumferentially via contact liquid, operating at a frequency of 10 MHz. The probabilistic-statistical characteristics of multiple reflection pulse series were analyzed. Their analysis shows that the detectability coefficient parameter is most stable in terms of detecting defects using bulk waves.
