This paper addresses the thermal analysis of self-propagating high temperature synthesis (SHS) in joining operations of temperature sensitive materials. A parametric finite element analysis of SHS is conducted, i.e. the influence of reaction rate, ignition temperature and reaction zone thickness on reaction stability and velocity is investigated. Special regard is given to surrounding materials such as amorphous alloys in joining operations. These materials act as heat sinks that conduct energy away from the reaction zone and thus diminish or even extinguish the reaction. In addition to the numerical simulation, analytical relations are developed to introduce criteria for reaction stability. Analytical and numerical results are compared for verification.
► Finite element analysis of self-propagating exothermic reaction. ► Parametric study of thermal propagation. ► Novel analytical model for the prediction of reaction stability. ► Excellent agreement of analytical and numerical solution.
