HEAT CONDUCTION AND HEAT TRANSFER IN TECHNOLOGICAL PROCESSES

FINITE-ELEMENT MODEL OF TEMPERATURE CONDITIONS IN SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS OF CYLINDRICAL BLANKS
V. L. Kvanin, N. T. Balikhina, P. I. Krasnoshchekov, V. P. Radchenko, and A. F. Fedotov UDC 621.1.016.4 Two-dimensional, nonstationary heat-conduction problems in a system of four finite bodies with an internal mobile heat source of the first kind (burning front) have been solved by the finite-element method. The influence of basic technological factors on the temperature-field parameters in the process of synthesis of TiB-40% Ti alloys has been investigated. It has been shown that for a real technological cycle the temperature field in a blank and a sand shell can be considered to be stationary and homogeneous.
