Role of TiCN addition on the characteristics of reactive spark plasma sintered ZrB2-based novel composites

The present investigation was carried out to illustrate the effect of TiCN on the microstructure development of spark plasma sintered fully dense ZrB2-based ceramics. The microstructural observations, X-ray diffraction patterns, and field emission-electron probe microanalysis revealed the presence of the (Zr,Ti)B2 and ZrCN phases in the final microstructures of the prepared composites. The advancement of a chemical reaction between TiCN and ZrB2...
