Paper Title:
Synthesis of Al2O3 Reinforced Ti3AlC2 In Situ Composites from Ti, Al, TiO2 and C
  Abstract

Al2O3 reinforced Ti3A1C2 in situ composites have been fabricated by reactive hot pressing method from the mixture of Ti, Al, TiO2 and C. The phase formation and transformation regularity of samples during the process of hot pressing were investigated in detail by X-ray diffraction (XRD). The microstructures of the synthesized samples were observed by scanning electron microscopy (SEM). The results show that the reactions of powder mixture during the hot press sintering could be divided into three stages: firstly, Ti reacted with Al to form TiAl intermetallics, and Ti reacted with C to form TiC, respectively; and then TiO2 was reduced by Al to form Al2O3, TiAl intermetallics reacted with TiC to form Ti2A1C; finally Ti3A1C2 was formed through the reaction between Ti2A1C and TiC.
