摘要：
The kinetics of the reaction of synthesis of titanium aluminide from binary (Ti - 48% Al), ternary (Ti - 48% Al - 2% Cr, Ti - 48% Al - 2% Nb) and quaternary (Ti - 48% Al - 2% Cr - 2% Nb) mixtures of elementary powders is studied. Differential scanning calorimetry in heating of the powder mixtures is used to determine the temperature and heat of formation of titanium aluminides and the kinetic parameter and activation energy in the Johnson - Mehl - Avrami equation.
