| Abstract |
Microstructural evolution of Ti-C-metal binder powder mixtures during SHS process was investigated by combustion-wave arresting technique. Al, Fe, Co, Ni and Cu were selected as binder metals of TiC-based cermet. The characteristics of SHS reaction occurred in different mode, depending on the binder metals. SHS reaction resulted in the three distinct regions; such as unreacted, partially reacted, and fully reacted parts. The intermediate phases of Ti and the metal binder were formed in the partially reacted region. The resulting cermet in the fully reacted region consisted of round shaped carbide particles and metal binder phase. |
