LAWS OF MOTION OF THE EXOTHERMIC REACTION FRONT IN A POWDER MEDIUM

A constitutional function for a bistable cellular automaton is present ed which is universal for numerous processes. The bistable cellular au tomaton formalism was used to describe the propagation of a combustion (switching) wave in a chemically active medium. The calculated depend ence of front velocity on the initial state and properties of a system was used to describe the synthesis of Ni3Al in a powder mixture. The calculated results were in good agreement with experimental data. The relationships obtained permit calculation of the important technical p arameters for synthesis in the combustion regime.
