RÉSUMÉ

Sequential analysis of a diffusion model, widely applied for describing the kinetics of heat-release in SHS of refractory compounds, using real values of diffusion coefficients and experimental data for synthesis of titanium, carbide, was made. Variation of the reaction cell geometry in melting of the metallic reagent is taken into account. The condition for breaking the primary product crust, resulting in the flow of the liquid metal in the SHS wave, was determined. It was shown that the quasiequilibrium theory of diffusion-controlled interaction does not provide sufficient heat release to maintain the combustion wave, and only hollow particles of interstitial (carbides, nitrides, and borides) can generate within its framework. Qualitative nonequilibrium mechanism of phase formation, allowing explanation of experimental results, was proposed.
