Ys. Zhang et Gc. Stangle, A MICROMECHANISTIC MODEL OF THE COMBUSTION SYNTHESIS PROCESS .2. NUMERICAL-SIMULATION, Journal of materials research, 9(10), 1994, pp. 2605-2619
A series of computer experiments was conducted for the self-propagatin
g combustion synthesis process in the Nb-C system, based on the genera
l theoretical model that was developed previously.(1) A detailed and q
uantitative description was given for the various physical and chemica
l processes that take place during the combustion synthesis process. T
he results are presented at various length scales in order to provide
an insight into understanding the mechanisms that are responsible for
the self-propagating behavior. It was shown that a fundamental underst
anding and precise control of the process require a strong emphasis on
the joint contributions of the rates of the various mass and energy r
edistribution processes that occur during the combustion synthesis pro
cess. A proper balance of each of the elementary process rates must be
achieved to give rise to self-propagating behavior. This paper illust
rates some of the capabilities of the general theoretical model in qua
ntitatively describing the self-propagating combustion synthesis proce
