摘要：

Titanium carbide (TiC) was consolidated with 20 mol% zirconium carbide (ZrC) by spark plasma sintering in the temperature range of 1773-2473 K, and the phase formation, microstructure, relative density and mechanical properties were investigated. The composite consisted of Ti-rich (Ti, Zr)C and Zr-rich (Zr, Ti) C solid solutions at 1773-2373 K, and was single-phase (Ti, Zr) C at 2473 K. The relative density of the composite was over 98% above 2073 K. The composite prepared at 2273 K exhibited the maximum H-V of 29.7 GPa with the K-IC of 3.76 MPa m(1/2).
