摘要：

A brief outline of thermal structure investigations of self-propagating high-temperature synthesis (SHS) of metal-boron, metal-silicon and metal-carbon is given. Multi-stages (multi-zones) of synthesis wave are revealed. Relative reaction zone sizes (wide or narrow) are defined. Positions in the wave of the stages governing the propagation rate are found. A chemical scheme of titanium silicide synthesis is suggested. Profiles of the volumetric heat release rate in the wave are obtained from experimental temperature profiles which permits to establish formal kinetic laws. Interpretations of these laws are proposed. © 1990 IUPAC
