Ti-Si-C MAX phase system

In this study, the processing of Ti3SiC2 MAX phase was carried out using pure Ti, Si and C powders. The prepared mixture was heat treated at temperature between 1300-1500 °C, for various holding times. There were numbers of peaks on the TG/DTA curves which indicate thermal behavior of the starting composition and the formation of the aimed phase. At temperature 1400 °C and above, titanio-silico-carbide phase was detected as a major phase in the heated samples. It was observed that, the silicon content of the starting mixture was decreased ant the formation of 312 phase of the Ti-Si-C system. At lower temperature SiC was formed but the silicon content of the starting composition was crucial point on the formation of MAX phase. TiSi, SiC, TiC and Ti3SiC2 phases were detected in the sintered samples.
