By the finite-element method the problem of nonstationary 
heat conductivity in the system of three bodies of finite sizes with 
an internal moving source of the first kind (burning front) has been 
solved. The influence of various factors on the temperature field 
parameters under HTS pressing of alloys of the Ti-C-Ni system 
has been investigated. It has been found that in the synthesis products 
internal cooling conditions under which the contact surface temperature 
behind the burning front remains constant are realized and temperature 
equalization throughout the blank volume occurs. Under internal cooling 
conditions the material has the highest plasticity and compactability.
