Purpose of work - to establish, on the basis of theoretical and experimental studies, the regularities of nonequilibrium processes during reaction sintering, which provide active shrinkage and formation of the microcrystalline structure of complex metal compositions. To develop recommendations for the creation of new functional sintered materials with increased erosion, wear and heat resistance. Research methods - theoretical and experimental thermokinetics, technological means of powder metallurgy, x-ray and microstructural analysis, physical and mechanical tests, etc. Thermokinetic studies of the interaction mechanisms in powder preforms based on nickel systems with aluminum, titanium, tin and other metals have been carried out. Methods of manufacturing specimens of rolled metal sheets of dispersion-hardened powder nichromas, their thermo-reaction soldering, and models of heat-shielding cell panels for use in reusable spacecraft have developed. The scientific principles of control of processes of creation of heat-resistant materials and obtaining of pseudo-alloy Mо25W-20об.%Cu with high plasticity and relative density of 97,5-99,5% have been developed.
