摘要：
A large amount of TiC hexagonal platelets has formed on the surface of the sample made of Ti/Si/TiC/Al-0.2 after sintering at above 1450 degrees C in an Ar atmosphere. The basal plane of TiC platelets is (111) facet confirmed by X-ray diffraction. Small amounts of Si and Al elements dissolved in the TiC crystal structure, influencing the structure of TiC. The detailed structure and growth mechanism of the TiC platelets have been observed and analyzed. A model has been proposed to understand the formation of TiC hexagonal platelets.
