    Abstract

    An analytical investigation of regularities for propagation of combustion front in the chemically-active systems was undertaken with the use of bistable media formalism. By the example of self-propagating high-temperature synthesis of Ni3Al intermetallic compound, the scheme of numerical simulation is described for propagation of exothermal reaction front. It is found that the change of powder mixture ignition temperature and the morphological characteristics of powder mixture particles markedly influence on the front propagation rate.
