Announce of the International Symposium on Bulk Nanostructured Materials

General information

  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 field of NanoScience and Technology.

  According to ISI's current ranking, four researchers whose interests are focused in this area occupy positions in the top ten of most-cited 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 and alloys.

  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 materials science.
