A search for novel materials demonstrating challenging physical properties and phenomena, which are prospective for development of new technologies is one of primary topics in modern multidisciplinary scientific research in the fields of materials science, condensed matter physics, chemistry, biophysics, medicine, etc. In order to reveal the key features of formation of physical properties of crystalline, nanostructured and massive materials, one needs to apply research methods allowing to obtain information at different scopic level: micro, nano or micron scale. Neutron scattering methods –diffraction, small angle scattering and radiography offer wide range opportunities for research of materials. Neutrons have a number of specific properties, making them distinguished from other elementary particles – absence of electric charge, presence of magnetic moment, different scattering amplitude for different isotopes of one atom, large penetrating depth, energy comparable with energy of dynamic lattice excitations. This is a short overview of interesting scientific results obtained by neutron scattering on the basic facilities of the high flux pulse IBR-2 reactor. These results extend from studies of structural and magnetic phase transitions at high pressure, or the peculiarities of nanostructural organization in optical materials, to studies of the structural inhomogeneities in the turbine blades or iron-stone meteorites. Those reported results are brilliant examples of the possibilities of neutron facilities at the IBR-2 reactor for a research of the structural organization of any materials.
