C. He et Gc. Stangle, A MICROMECHANISTIC MODEL OF THE COMBUSTION SYNTHESIS PROCESS - MODES OF IGNITION, Journal of materials research, 13(1), 1998, pp. 135-145
A theoretical model of the combustion synthesis process has been devel
oped to study the ignition of a self-propagating combustion synthesis
process in the Nb-C system. Compared with most of the previously publi
shed theoretical work on this subject, this model provides a much more
detailed description of the combustion synthesis process from a micro
scale point of view, due to the fact that it takes into consideration
the various microprocesses, such as the melting of reactants, the diff
usion and mixing of reactants, and the formation of products. Differen
t ignition modes, including constant-temperature ignition, constant-he
at-flux ignition, and variable-temperature ignition, are considered in
this work. The key parameters that influence the ignition process are
also discussed.
