Notes:
DSC/TG analysis was used to investigate the change of TiSi2-SiC-N2 system in thetemperature range from room temperature to 1400℃. The relationships between $G and T about thereactions possible occurring in TiSi2-N2 system during combustion synthesis were calculated. In orderto study the combustion process in detail, the reaction of TiSi2-SiC-N2 system was stopped atdifferent stages by quenching the samples. The composition and microstructure in different reactionzones were analyzed by means of XRD and SEM, accordingly, reaction kinetic model ofTiSi2-SiC-N2 combustion system was established. The result showed that TiSi2 firstly reacted with N2to form TiN and Si, and subsequently Si were nitrified
