Abstract

The Chair “Physical Problems of Material Science” (National Research Nuclear University MEPhI (Moscow Engineering Physics Institute)) carries out the training of materials science specialists (bachelors, masters, engineers-physicists and candidates of sciences) with their ongoing participation in research work. This article gives the review of results of scientific researches, carried out at the Chair in the field of metallurgy, metal science and metal physics of nuclear engineering materials, obtained using non-ferrous metals (including zirconium alloys of various modifications and states; uranium alloys and compounds; vanadium alloys and rapidly quenched complexdoped alloys, based on titanium, zirconium, nickel, copper and aluminum). Development of new materials and new structural-phase states in complexdoped reactor alloys in ultrafast melt cooling process is considered together with influence of high-temperature pulsed plasma and subsequent heat treatment. Zirconium metallurgy field is focused on the following operations: research of formation of structural-phase states under mechanical change of alloys; research of regularities of texture changing in zirconium alloy products; research of hydrogen and oxygen behavior; research of surface modification; investigation of oxide films and diagnostics of their state; X-ray study of textural changes, taking place in metal materials; investigation of behavior of helium and hydrogen in vanadium alloys. Research results of uranium, its alloys and oxides are also presented in this article, together with technological and innovative developments. The field of condensed matter physics gives an overview of the results of self-diffusion and interdiffusion in alloys; influence of external factors on diffusion processes in materials; and characteristics of point defects and their interaction by simulation.
