ulk nanostructured materials produced by severe plastic deformation (SPD)
are materials with nanostructured features, such as nanograins, nonoclusters
or nanotwins. These nonstructured materials are fully dense and contamination
free and in many cases they have superior mechanical and functional properties.
Due to the high hydrostatic pressure during plastic deformation, also very brittle
materials can be deformed to infinite deformation degrees. These highly deformed
materials have shown highlights in mechanical properties i.e. high strength
paired with considerable ductility, as well as superplasticity at high deformation
rates, recent research activities increasingly present outstanding SPD functional
nanomaterials. Those exhibit advances in radiation damage resistance, electrical
conductivity, hydrogen storage and especially thermo electricity where even world
records in both p- and n-type semiconductors were broken. This review provides a
summary of some of these recent developments. Special emphasis is placed on
the use of SPD processing in achieving increased thermo electricity, an improved
hydrogen storage capability, materials for use in biomedical applications, and the
fabrication of high-strength metal-matrix nanocomposites.
