ABSTRACT:
The depth of a case on a specimen of case-carburized steel is measured by launching an acoustic wave along the surface of the specimen such that the wave passes through the case, and measuring the velocity of that wave within the specimen. From an existing correlation of velocity and case depth for the very same core steel as the specimen, one finds the case depth which corresponds to the measured velocity, and that is the case depth of the specimen.
