Limits of the self-propagating high-temperature synthesis wave propagation in eutectic composite materials

Abstract

Phase formation during the self-propagating high-temperature synthesis in the Ti-C-M (M = Ni, Co, Cr) eutectic-type ternary systems with and without preheating has been studied. It was found that the synthesis proceeds via origination of quasi-binary TiC-M eutectics, the principle reaction being that of TiC formation. The dependence of the combustion temperature on the preheating temperature and the initial charge composition has been evaluated by thermodynamic analysis.
