In this paper study the microstructure of the wave self-propagating high-temperature synthesis (SHS) to find the relationship between the rate of the reaction front, the characteristic size of foci and the combustion temperature. Measure the dynamics of the temperature field SHS process was carried out using of the original optical complex of micropyrometer with a spatial resolution of 5.9 mkm and a speed of recording up to 10,000 frames per second. A method of analysis of thermal data implemented on the basis of ergodic model of the wave regime SHS and MATLAB. In the experiment is varied composition Ni-Al and its initial temperature. The experiment results approximated of the quadratic dependence of the rate of the front reaction on the hearth size, and inverse dependence of the hearth size on combustion temperature and initial temperature of the reaction mixture.
