Description

The main purpose of the research is to develop the scientific foundations of breakthrough foundry MHD-plasma technologies for obtaining a new generation of cast structural and composite functional materials on a metal basis. The conceptual basis of the project - modern scientific ideas in the field of the theory of rare-metal systems, metastable microhomogeneity and MHD-plasma methods, including amplitude-frequency, influence on it: electromagnetic actions for control of processes of heat-fracture transfer in processing metal melts of refining, modifying, microalloying and composite additives in various aggregate states (solid, liquid, gaseous or vaporous) with immersion pla-trons to create a controlled artificial microneedon the identity and impartation of substantially improved or special structure and substantially enhanced or special solid properties to the developing metallic materials. Achievement of this goal was ensured by the implementation of a unique concept of research. It is based on the integrated use of external energy effects (deep low-temperature plasma, controlled magneto-hydrodynamic currents) on rare-metal systems in their electrophysical thermo-power treatment, the introduction of metal and non-metallic additives, in particular, bringing them to the surface, with the subsequent transfer of the melt and additives by means of a plasmatron in the reaction zone (temperature - 3000-5000 K) of the magnetodynamic mixer-dispenser into a high-reaction state (steam), by ezpechennya flow physico-chemical and interfacial interactions to form new vapor phase and creating in the process of further condensation in the cooling liquid metal matrix (temperature - 1000-1100 K) vysokohradiyentnyh conditions - concentration and temperature (cooling rate of more than 104 K / s). The implementation of such a complex MHD-plasma action allows to overcome the main disadvantages of the existing technologies for the forced introduction of reinforcing particles into metal matrix melts upon receipt of composites, namely: floating or immersion of introduced particles, their not assimilation and even "rejection" of non-matrix matrix melting. naked incoherence to it, coagulation and sticking of fine particles during processing, uncontrollability of their volume distribution, etc.5481
