Summary

A general formulation in terms of temperature-enthalpy relationship has been proposed to simulate self-propagating combustion synthesis of MoSi2 and SiC-reinforced MoSi2 This new approach takes into consideration the effects of possible phase changes during the combustion process and also considers various micro-structural parameters such as porosity of the powder compact, compositing phase content, etc. Various parametric studies have been made to demonstrate the feasibility of such a modeling approach by analyzing the effects of initial porosity in compacts made of Mo, Si, and SiC powders, volume fraction of SiC powder content, etc. The model predictions for the combustion pattern are in close agreement to those generally observed in similar combustion experiments.
