Numerical experiment of Mg_2Ni combustion synthesis was carried out by an experimentally validated, total mathematical model, in which effect of preheating of metals on reaction temperature, reaction time, reaction degree and reaction mode was assessed. The feature of the mathematical model was to have a general rate equation with solid combustion and liquid-trigger combustion at an eutectic temperature, and to consider the influence of latent heat due to melt of an eutectic composition. The calculated data gave transient fields of temperature and reaction degree within a sample at various preheating temperatureS. The results showed that the preheating of metals offers benefit in increasing maximum temperature, shortening a processing time, enhancing purification of a product and dominating solid combustion mode without liquid phase generation.
