摘要：

The association between the ultrasonic damping coefficient and the frequency of the maximum amplitude of the spectra (FMAS) of the ground signal is theoretically and experimentally examined. Based on the known dependencies of the ultrasonic damping in cast iron on the physical-mechanical properties, for example, hardness, a method is proposed for the non-destructive testing of these properties based on the FMAS. An example is given for a particular grade of cast iron.
