This paper is concerned with the problem of use of phenomenological kinetic model of chemical reactions in the porous Ti-C and Ti-B powder mixtures under high velocity impact. Effects of high shock pressure and high temperature are presented by variation of constants involved in the model. A powder mixture is treated as a single distended solid having thermomechanical properties based upon the mass-averaged quantities of the powder mixture. The density changes resulting from chemical reactions have been considered. The energy from the heat release is included in energy conservation equation, and contributes to pressure increases through the equation of state.
