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
