Modeling of thermokinetics of intermetallides synthesis in the ti-al reacting system at heat transfer by thermal conductivity and radiation

Abstract

Within the framework of a mathematical model that takes heat transfer into account by thermal conductivity and thermal radiation, the processes in the Ti-Al powder reacting system under contact melting are described. The effect of the rate constant of the synthesis of intermetallic compounds Ti₃Al, TiAl, TiAl₂, and TiAl₃ on the thermokinetic behavior of the reacting system is studied. With the help of a computer experiment, the role of thermal radiation in the high-temperature synthesis processes of each intermetallide is investigated as a function of the rate of exothermic reaction processes occurring in the system.
