Abstract
A model of synthesis was proposed and theoretically investigated via combustion of a composite in mechanically activated Ti–C, Ti–B, and Ti–Si powder mixtures. The effect of mechanical activation on synthesis modes was explored by introducing special activation parameter. As demonstrated by calculations, with its increase, the maximum temperature in the reaction wave is decreased during the reaction; combustion concentration limits are expanded and the propagation velocity of the reaction front is increased.
