Résumé : Surface acoustic waves generated and detected by a laser-ultrasonic system are used to characterize graphite precipitates in cast irons. Measurements of velocity and amplitude as a function of frequency are performed in samples with nodular, vermicular and lamellar forms of graphite. The results show that the ultrasonic parameters allow classifying very clearly these different cast iron types. © 1998 Elsevier Science S.A. All rights reserved.
