A two-dimensional problem of nonstationary heat conduction 
in a system of three bodies of finite size with an inner movable source 
of the first kind (combustion front) has been solved by a finite-element 
method. The effect of different factors on the parameters of a temperature 
field in self-propagating high-temperature synthesis pressing of alloys 
of a Ti-C-Ni system has been studied. It is found that a regime 
of internal cooling is realized in the synthesis products, when the 
temperature of the contact surface behind the combustion front remains 
constant and evens out over the volume of a blank. In the regime of 
internal cooling, the material has the highest plasticity and compactibility.
