Nondestructive Evaluation of Microstructure and Stresses in Steels

The paper presents an overview of the nondestructive methodologies developed at the author's laboratory for characterization of microstructural features in various steels such as ferritic, austenitic stainless and manag-ing steels. The emphasis is given on the judicious sel-ection of a single non destructive evaluation non dest-ructive evaluation (NDE) technique/parameter or multi-technique/ mult-parameteric approach for comprehensive characterization of microstructural/substructural changes occuring in steels, based on the indepth understanding of the materials response to the specific form of energy imparted during NDE.
