Purpose - to create the theoretical foundations of optimization of modes of forced mixing during crystallization of ingots and castings, the development of thermophysical model of temperature and stress fields during quenching of steel balls, the development of methods of using low-energy ion beams to assess the properties of uranium compounds, the determination of optimum parameters of pulsed-plasma treatment of metals and alloys. Methods of research - experimental and analytical study of the hydrodynamics of mixing liquid steel, the use of low-energy beams, microstructural analysis, hardness tests, numerical modeling . In the first chapter the effect of specific power stirring molten steel at the process of crystallization is analyzed. In the second section, a mathematical model of hydrodynamic fluid is developed basing on the principle of "smoothed particles". In the third section the model of calculation of the temperature and stress fields in the steel balls during heat treatment. In the fourth section the experience of using low-energy ion beams to assess the properties of uranium compounds is described. In the fifth section the influence of the parameters of mode of pulse-plasma treatment on the mechanical properties and microstructure of the modified steels with different carbon contents is analyzed.
