Abstract: By means of laser ultrasonics,we have used Rayleigh waves to study four cast-iron samples with different morphology of graphite precipitation. The frequency dependence of the wave attenuation and velocity were obtained in the range 0-30 MHz. In this frequency range the ultrasonic attenuation for ail samples was found to be proportional to the square of the frequency while the velocities,although clearly different between different samples were found non-dispersive. The mechanism of the attenuation for cast-iron is discussed and the link between microstructural sample properties and wave propagation properties is discussed.
