Numerical study results are presented for quenching of refractory material samples produced by self-propagating high temperature synthesis. Heat transfer calculations have been accomplished assuming that high speed water jet is forced normally to the sample surface. A set of equations has been formed within the framework of thermal theory of condensed system burning and on the assumption that chemical reactions of high temperature synthesis are of two-stage nature. Calculation results are represented as diagrams of spatial distribution of volume concentration of intermediate combustion product and cooling rate of the sample. It has been shown that high speed cooling technique makes it possible to fix sufficient content of intermediate products for separate regimes of self-propagating high temperature synthesis.
