SHS of NbSi2:: A comparison between experiments and simulations

Computer simulation results for the Self-propagating High-temperature Synthesis (SHS) of the intermetallic compound NbSi2 are discussed in comparison with experiments for SHS of mechanically activated powders. The variation of wave speed of the propagation front is considered while varying Nb grain size and thermal conductivity of the starting mixture. A co-operating effect of these two parameters (due to the change in morphology of reactants after milling) is outlined.
