The Institute was founded in 1995 as an organization department of Ufa
State Aviation Technical University. The research at the Institute is
focused on the development of bulk nanostructured materials for advanced
applications using severe plastic deformation.
Severe plastic deformation (SPD) is one of the most successful "top-down"
approaches of synthesizing nanostructured bulk materials based on imposition
of extremely large plastic strains on materials. Such strains result in a
very fine dislocation substructure that in certain conditions evolves into
a granular structure with high-angle grain boundaries. The SPD methods are
capable of producing nanostructured materials with grain sizes refined down
to about 100-300 nm, and in some materials down to about 30 nm.
Processing of ultrafine-grained and nanostructured metals and alloys by
SPD techniques was pioneered by Prof. R.Z. Valiev and co-workers in the
early 1990's. The most developed SPD processing methods are high-pressure
torsion (HPT) and equal-channel angular pressing (ECAP). Due to top-level
publications of the Institute's researchers in this area, nanocrystalline
materials fabricated by SPD methods have become a new, world-wide recognized
NanoScience and Technology.
According to ISI's current ranking, four researchers whose interests are
focused in this area occupy positions in
the top ten
researchers in Materials Science: T.G. Langdon, Z. Horita, M. Nemoto,
and R.Z. Valiev.
It has been recognized that SPD is a versatile method of nanostructuring,
which allows for the fabrication bulk nanocrystals out of various metals
At present the Institute conducts investigations in the field of physics
and mechanics of severe plastic deformation, development of SPD processing
methods, fundamental studies of the structure, mechanical and functional
properties and performance of SPD processed nanocrystals. Practical
applications of bulk nanostructured materials in Mechanical and Aerospace
Engineering and Medicine are of special importance. These works are carried
out together with other subdivisions of the University and in close
cooperation with Russian and international research centers.
The Institute occupies 1000 sq.m. and has unique facilities: original
die-sets for severe plastic deformation by high pressure torsion and
equal-channel angular pressing, hydraulic presses with capacities of
100, 150, 250 and 1000 tons, vacuum chambers for powder compaction,
transmission electron microscope, X-ray diffractometers, differential
scanning calorimeter, microhardness measuring systems, mechanical testing
machines and other instruments. Specialized machine for mechanical testing
of miniature samples has been constructed and under use at the Institute.
The Institute successfully combines research and academic activities.
The specialists of the Institute supervise doctorate and habilitation
theses at the Institute and Departments of Physics and Nanotechnology
of the University. The scholars work at reknown Materials Science research
centers over the world.
At present the Institute has a total staff of about 50, including 33
researchers, among them 7 Doctors of Science and 12 Candidates of Science.
The Institute closely cooperates with Russian and foreign centers for
