This review addresses the structure and phase formation mechanisms of self-propagating high-temperature synthesis (SHS) of single-phase complex carbides Ta-Ti/Zr/Hf-C, as well as the consolidation of synthesized carbides by various sintering methods. Properties of the synthesized and consolidated complex carbides are described, and unique advantages of SHS method for the synthesis of ultra-high temperature complex single-phase carbides are highlighted.

“…The modern promising method for creating refractory materials is the Spark Plasma Sintering (SPS) (used in this paper). Its advantages over the more classical hot pressing method were demonstrated in [7] for the Ta-Hf-C system. However, the publications about the SPS obtaining materials in the Hf-C-N system are absent.…”

Phase Formation and Densification Peculiarities of Hf–C–N Solid Solution Ceramics during Reactive Spark Plasma Sintering

Herein, phase formation and sintering of hafnium carbonitride ceramics from a 4HfC-3HfN powder mixture using reactive spark plasma sintering are studied. X-ray diffraction (XRD) data show that the mutual heterodiffusion of carbon C and nitrogen N increases with sintering temperature within the studied temperature range 1500-2100 C. 4HfC-3HfN powder sintering at 1900 C for 5 min under 60 MPa pressure yields HfC x N 1Àx solid solution ceramics. The ceramic sample prepared under optimal conditions (2100 C, 5 min, 60 MPa) is characterized by an average grain size of 10 μm, microhardness of 19.6-22.5 GPa, and relative density above %97%.
