Mathematical modeling of structure formation during combustion synthesis of advanced materials

摘要: Abstract The synthesis of advanced materials by a wave heterogeneous combustion propagating through charge mixture, or the so-called self-propagating high-temperature (SHS) has many potential advantages over conventional techniques synthesis. Because high heating rates, steep temperature and concentration gradients, fast accomplishment reactions, mechanisms physical, chemical structural transformations in SHS are intricate often not known. Further understanding interaction waves, relating process parameters to structure properties target material, application producing final articles necessitates developing mathematical models for SHS-related phenomena. Various aspects modelling discussed this paper. They include analysis novel factors influencing formation, viz. heating-to-reaction mass transfer-to-reaction time ratios, autocatalysis intrinsic stochasticity, which unnoticed traditional methods. thermodynamics theory processes is outlined. Novel developed on condensed systems, involve stochastic effects autocatalysis. New solid-gas systems worked out, reaction kinetics transfer gaseous reactant permit predicting formation pattern wave. Application porous means discussed.
