| Abstract Scope |
The formation of multi-component single-phase ultra-high temperature ceramic (UHTC) materials has been an area of research in recent years, with preliminary results indicating enhanced hardness when compared to traditional UHTCs. (Ta,Nb,Hf,Ti)C was batched and reached a relative density of over 99% via spark-plasma sintering. Vickers microindentation yielded a hardness value of 24 ± 2 GPa and a fracture toughness value of 3.8 ± 0.7 MPa∙m1/2. |
