Numerical study of thermal processes by matter hardening in SHS wave

Estimations of cooling rate of sample, subjected to self-propagation high-temperature synthesis wave (SHS) have been made. For new structures properties keeping in SHS products the heat-removal rate of 10⁴ K/s is necessary. The numerical investigation of combustion front quenching has been carried out on the example of titanium - carbon system. Rates of sample cooling due to heat conductivity or drop-liquid evaporation are shown to be insufficient. Necessary cooling rate, according to calculations, can be reached by convective heat exchange with high-velocity flows of low-melting-point metals, water or cryogenic liquids. Dependences of cooling rate on temperature in various zones of combustion rate have been calculated for water flow.
