Consolidation of Titanium Carbide with Zirconium Carbide by Spark Plasma Sintering

Abstract:

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.
