Increased strength characteristics give a possibility to decrease
weight and size of implants, which allows to accelerate recovery
of a patient.
The last decade has seen the development of a new research area in
materials science, consisting in fabrication of bulk nanostructured
materials (i.e. materials with a microstructures refined down to
less than 100 nanometers) using advanced processing methods,
namely, severe plastic deformation (SPD). This exploratory area
is now known as NanoSPD. Nanostructured materials produced using
SPD methods are characterized by enhanced service properties,
especially mechanical ones. Under development are the technologies
of producing nanostructured semi-products out of Ti-Ni alloy with
extraordinary properties (including shape-memory effect) for medical
and structural applications.
