Notes:
The reaction process and kinetics of Al-TiO2-C-Ti-Fe system were investigated by differentialscanning calorimetry (DSC) analysis, X-ray diffraction (XRD) analysis and scanning electron microscope(SEM). In order to obtain the information of reaction process for complicated system, the reactioncharacteristics of Al-TiO2, Al-TiO2-C and Al-TiO2-C-Ti systems are explored firstly. The results showthat the reaction process varies with temperature in Al-TiO2-C-Ti-Fe system. At the lower temperature,the dominating reaction in Al-TiO2-C-Ti-Fe system is that between Al and Ti, Al and Fe, and so TiAlx,FeAlx, and Ti2Fe intermetallic compounds form. With the temperature increasing, the intermetalliccompounds are decomposed. Then the decomposed Ti and Al react with C and TiO2 respectively and thestable TiC, Al2O3 and Fe three phases form in the final product
