K.B. Zhogova, V.N. Piskunov, G.G. Savkin, V.P.Neznamov Nanotechnologies and “Tailored” Materials RFNC-VNIIEF fundamental results in nanomaterials and nanotechnologies 1. INTRODUCTION 1. INTRODUCTION Nanomaterial manufacturing methods used in the RFNC-VNIIEF: Mechanical activation, Intensive plastic deformation, Three-dimensional modifying, Plasma and detonation sputtering, Self-propagating synthesis Sol-gel method Developed: “Carbonit”, the material with ultra dispersed structure and enhanced strength and fire resistance Developed: “TUMaN” technical-grade carbon material with nanopores Obtained: Highly porous nanostructural nickel Using the equichannel angular pressing (ECAP) method, volumetric nanostructural materials were obtained. Obtained: Samples of polymer materials with improved characteristics Technologies to obtain protective coatings using plasma and detonation sputtering of ultra dispersed materials developed Numerical simulation methods developed to describe gas diffusion in metals and material destruction processes under dynamic loading Molecular dynamics codes were used in the calculations. These techniques are used to compute the behavior of hydrogen and its isotopes in structural materials; describe mechanical properties of nanostructural metals; and simulate nanomaterial manufacturing technologies and functional properties. * Thematic International Conference on Bio-, Nano- and Space Technologies Development of materials with predetermined properties (i.e. “tailored” materials) is one of the key nanotechnology areas that may bring positive effects in the nearest perspective. For the recent decade VNIIEF has been pursuing the RD(s) in nanomaterials. Primarily, the efforts are focused on the functional characteristics upgrade of consolidated nanomaterials, i.e.: metals, ceramics, polymers and coatings. Nano Objects: Carbon nanostructures (fullerenes; nanotubes; nanofibers); Nanocomposites resulting from mechanical activati
