Thermodynamic and Kinetic Considerations in Production of y-TiAl by KRH Combustion Synthesis Process

KRH is a new combustion synthesis process for production of gamma titanium aluminide. This process is on the basis of reaction between TiC^, Al, Ca and KCIO4. Thermodynamic and kinetic considerations of KRH process has been investigated in this article. On the basis of measurements, this process ignites at 505°C and temperature reaches to 1950°C. On the other hand, thermodynamic calculations showed that the maximum temperature of system is 2050°C. These temperatures are high enough for melting of TiAl and CaAU07 and evaporation of KC1.
