| Özet |
| In this research, binary 4TaC-HfC based composites were consolidated using carbide materials and addition of 0-15 vol.% MoSi2 by means of spark plasma sintering at 2000 °C. The nearly full dense and monophase specimens were fabricated with a relative density value higher than 99%. Mechanical tests revealed values of 18-19 GPa and 4-4.3 MPa·m1/2, for average Vickers hardness and fracture toughness of the composites, respectively. Analysis of linear shrinkage during densification revealed that MoSi2 addition increased densification rate and decreased the time required to reach full density at 2000 °C. It is proposed that at the intermediate stage of sintering, mass transfer can be accelerated by formation of a silicide based liquid phase and viscous flow mechanisms. The formation of binary 4TaC-HfC solid solution phase enhanced the densification process at the final stage of sintering. |
