This paper reviews research on nanostructured high strength wires and strips. Such materials have sufficient ductility and they have found application in a variety of areas. The high strength of the materials is achieved by refinement of the spacing between the strengthening fibers. Due to the refined microstructure, the materials have very large interphase interface areas. Such interfaces provide very effective barriers for dislocation motions. In spite of their microstructural refinement, the materials still have sufficient ductility that gives them engineering values.
