Rapidly quenched (RQ) amorphous / nanostructured materials have been addressed in relation to their properties targeted towards potential applications. Quenching techniques like melt spinning and in-water quenching for production of these materials in the form of ribbons and microwires production respectively have been addressed. CoFe-based microwires exhibited interesting giant magneto-impedance (GMI) behviour and was used in development of GMI sensor for detection of carburization in austenitic stainless steel. Efforts have been laid on the production of Fe-based magnetostrictive amorphous ribbons and their potential use in magnetostrictive sensor (MsS) for generation of guided waves for detection of defects in pipes. Compositional tailoring has also been carried out in amorphous / nanostructured ribbons to raise the saturation magnetization beyond 1.6 Tesla. Some of these ribbons have also been found to manifest interesting electromagnetic interference shielding effectiveness (EMI SE) properties.
