Combustion, Explosion, and Shock Waves Aims and scope

Abstract

Laws of self-propagating high-temperature synthesis in 3Ti + 2BN reactive mixtures after preliminary mechanical activation in a planetary ball mill are studied. A discontinuity caused by specific features of the dynamics of formation of mechanocomposites is observed on the plots of the burning rate and temperature versus time. Regimes of preliminary activation are determined, which ensure the solid-phase combustion regime. Results of x-ray diffraction phase analysis and electron microscopy of combustion products and initial mixtures for different times of mechanical activation are presented.
