N2 - Ultrasonic velocity and attenuation data are presented on three types of hardened steel corresponding to three different applications: carbon steel for ball bearings, pearlite steel for rail steel and case hardened 1043 steel for general commercial application. The results include dispersion data for surface acoustic waves in the presence of a hardness gradient. An inversion technique is demonstrated for obtaining the hardness profile in good agreement with that obtained by conventional destructive means. Preliminary results are presented for a noncontact technique of measuring surface wave velocity.
