Abstract

This paper describes the application of a variety of methods to the nondesctructive characterization (NDC) of microstructure in hardened steels. The measurements include ultrasonic velocity, nonlinear ultrasonics, resonant ultrasonic spectroscopy (RUS), and magnetostriction. The materials used in the evaluation include bar and plate steels with quenched and tempered martensitic microstructures like 4340, 01 tool steel, and A710. No one method can characterize the microsturcture of hardened steels with repect to the strenth and hardness in different heat treated conditions alone. It is recommended that as many of these techniques as possible be used together for a thorough microstuctural evaluation.
