FINITE-ELEMENT AXIALLY SYMMETRIC MODEL OF THE THERMAL REGIME UNDER SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS OF BLANKS IN A FREE-FLOWING SHELL
A. F. Fedotov, V. P. Radchenko, and M. A. Ermolenko UDC 621.1.016.4 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. Samara State Technical University; email: mvm@sstu.edu.ru.
