| Abstract: | Ti3SiC2 ceramics are made of Ti/Si/C powder mixtures in the way of SHS. The phase formation process of Ti3SiC2 ceramics in SHS is examined by X-ray diffraction (XRD) of the combustion-synthesized product and differential thermal analysis (DTA) of the reactant system, which leads to the establishment of the corresponding physics model for the phase formation process of Ti-C-Si system in SHS. |
