Novel TiC-based composites were synthesized by reactive hot-pressing at 1800 °C for 1 h with ZrB2 addition as a sintering aid for the first time. The effects of ZrB2 contents on the phase composition, microstructure evolution, and mechanical propert

Reactive hot pressing was used to prepare (Ti,Zr)B2–(Zr,Ti)C composites from equimolar ZrB2 and TiC powders. The reaction and solid-solution coupling effect and enhanced densification in ZrB2-50 mol.% TiC were proposed as contrasted to conventional
