Abstract

This study evaluated ultrasonic pulse-echo angulation as a nondestructive technique for measuring thin case depths (less than 2 mm) in hardened steel. In concept, this method has been used to measure case depths greater than 2 mm and has also been suggested as a technique for determining nominal grain size. It has not been applied to case depths less than 2 mm because impediments, such as the obscuring effect of the front interface echo, the extremely low signal-to-noise ratio of grain backscatter, and the small area localization usually required by industrial inspection procedures prevent accurate measurement.
