EFFECT OF INTERLAMELLAR SPACING OF PEARLITE ON THE ATTENUATION OF ULTRASOUND

The attenuation of ultrasound was studied in samples of pearlitic steel taken from railway wheels containing between 0.53 and 0.61% carbon. A strong dependence of ultrasonic attenuation on grain size was observed; in addition a relationship was shown between the interlamellar spacing of pearlite in the steel and the attenuation coefficient. The scattering losses in the Rayleigh zone of the pearlitic/ferritic steel were found to be proportional to the spacing of the cementite lamellae in the pearlitic structure.
