英文摘要	In this paper, interfacial reactions between polymer derived SiC fiber and Ti3Si(Al)C2 were analyzed. Strong interfacial reactions occurred in 20 vol.% SiCf/Ti3Si(Al)C2 composite during the vacuum spark plasma sintering at 1350 ??C. At the begining, the Ti3Si(Al)C2 suffered spontaneous decomposition and resulted in the sublimation of gaseous Ti, Si and Al, and de-intercalation of TiC from the crystal structure, when it was combined with SiC fiber during sintering. Then, Ti reacted with the SiC phase and turbostratic graphite in the fiber and TiC was formed, and also Al was oxidized into Al2O 3. Meanwhile, most of gaseous Si released from Ti3Si(Al) C2 escaped from the outer surfaces of the composite under the compressive stress of 30 MPa and the vacuum environment, the rest Si was cooled into solid state following gas-solid reaction mechanism. ?
