The hardness depth of induction hardened steel parts can reportedly be analyzed rapidly and cost effectively by means of an ultrasonic microstructural analyzer (UMA) commercialized by Sonix Inc., Springfield, Va. The technology was developed by the Pacific Northwest National Laboratory and Delphi Saginaw Steering Systems.

Sonix holds the license from PNNL for commercializing the technology. The UMA makes measurements without the need for surface preparation and measures hardness depth on induction hardened, cylindrically shaped steel parts in less than a minute. Current destructive ...
